f' (x) The first derivative of a function See calculus If f (x) is equal to x^2 2x 5 then f' (x) is equal to 2x2 by ManMan36 Flag Get the f' (x) neck gaiter and mugWe set the denominator,which is x2, to 0(x2=0, which is x=2) When we set the denominator of g(x) equal to 0, we get x=0Explanation Using the defined function, f(a) will produce the same result when substituted for x f(a) = a 2 – 5 Setting this equal to 4, you can solve for a a 2 – 5 = 4 a 2 = 9 a = –3 or 3

F(x y z)=0 meaning
F(x y z)=0 meaning- f (x,y) is function in x and y If you draw this in R 3, the function will lie in the xyplane The domain of the function is the xy plane or some subset of it The graph of the function is the ordered triples (x, y, z) for which z = f (x, y) Example z = ln (xy) The domain is the portion of the plane for which xy > 0, which is the interior f (x) basically means y, and f' (x) means dy/dx The x can have a value, so for example, f (x) = 2x 1, then f (1) = 3 that is as good as I can explain it!!!

Solve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more Saying f (x) = 0 can mean different things depending on context If the function being defined, then it means that f (x) = 0 for all x, in which case your reasoning is correct Sometimes, though, it means that for a particular x, f (x) takes the value of zero, in which case f ′ (x) also being zero is notableWe say "f of x equals x squared" what goes into the function is put inside parentheses () after the name of the function So f (x) shows us the function is called " f ", and " x " goes in And we usually see what a function does with the input f (x) = x2 shows us that function " f " takes " x

The zero of a function is the xvalue that, when plugged into a function, makes the function equal to 0 f (x) means that we have a function of x The zero of the function f (x)=2x2 is the xvalue that makes f (x) = 0 So we can just set the function equal to 0, and then solve for x!How To Tell Where f (x) is Less Than 0 or Greater Than 0 Watch laterCritical Points Definition of a critical point a critical point on f (x) occurs at x 0 if and only if either f ' (x 0) is zero or the derivative doesn't exist Extrema (Maxima and Minima) Local (Relative) Extrema Definition of a local maxima A function f (x) has a local maximum at x 0 if and only if there exists some interval I containing x

Usually in basic math it means (f(x)) 2 But sometimes in a class like dynamical systems it will mean f(f(x)) In fact, I prefer the 2nd definition and to insist on writing (f(x)) 2 for the other term But mathematicians are extremely lazy and prefer to write things like sinx instead of sin(x), so I think I'm in the minority on thisThe Function which squares a number and adds on a 3, can be written as f(x) = x 2 5 The same notion may also be used to show how a function affects particular values Example f(4) = 4 2 5 =21, f(10) = (10) 2 5 = 105 or alternatively f x → x 2 5 The phrase "y is a function of x" means that the value of y depends upon the value of x, soIf f''(x) >0 on an interval, then f is concave upward on that interval d) If f''(x)

By $f(x) = x^2 4$ I am telling you that if you input a number $x$ to this function then the function squares $x,$ subtracts 4 and returns the result Thus for example if $x = 3$ then $y = f(3) = 3^2 4 = 9 4 = 5$ To graph this function I would start by choosing some values of $x$ and since I get to choose I would select values that make the arithmetic easy For example $x = 0, x = 1, x = 1$ The derivative, f' (x), can be interpreted as "the slope of the tangent line" f' (x)> 0 means all tangent lines have positive slope are going up to the right Also "if x> 0, then f' (x)< 90" so for x positive, the derivative is negative which means tangent lines are going down to the rightCould you explain to me how one should go about graphing functions such as f(x), f(x2), and so on Also, how should you explain things such as constants and relationships among functions?
