Answer :

f(x)=3/[tex]4\sqrt{x}[/tex] evaluate function f ' (3) =  [tex]-1/4.3 root 1/4[/tex]

f(x)=3/[tex]4\sqrt{x}[/tex] evaluate function f ' (7)=    [tex]-3/4.7root5/4[/tex]

How is a function evaluated?

Finding the value of f(x) =... or y =... that corresponds to a certain value of x is what it means to evaluate a function. Simply swap out all instances of x with the value of x to do this. For instance, x has been given the value 4 if we are asked to evaluate f(4).

root function illustration

F(x)=x f (x) = x is the square root function. The formula for the cube root is f(x)=3xf(x)=x3. A function that is defined by a radical expression is known as a radical function.
