Answer:


f(3x)=9x^2-3

Explanation:

One is given the following function:


f(x)=x^2-3

One is asked to evaluate the function for (
f(3x)). Substitute (
3x) in place of (
x) then simplify. Remember that a number raised to an exponent is the same as that number times itself the number of times that the exponent indicates. One can apply this logic here while simplifying,


f(x)=x^2-3


f(3x)=(3x)^2-3


f(3x)=(3x*3x)-3


f(3x)=(9x^2)-3


f(3x)=9x^2-3
