Evalute the function at the given value of the independent variable and simplify?

Question

f(x)=cubed3 +3/ x squared -3 ; f (3)

a. 2 b. 10/3 c. 5 d. 9/2

Answer 1

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

f(3)=30/6=5

Answer 2

Is it f(x)=3^3+3/x^2-3? The answer is c. 5.

Substitute the value of f(x) w/c is 3.

3^3 is equal to 27, then 27+3=30-numerator

3^2 is equal to 9, then 9-3=6-denominator

30/6=5
