Evaluate each funtion for the given input values:

for f(x)=4x-3,find f(x)when x=3

so is it f(x)=4(3)-3
f(x)=12-3
f(x)=9? is this right?

Yes!
ok thanks, i have one more question
Evaluate each function or the given input values:

for g(x)=x^3-x, find g(x) when x=(-3)

g(x)=(-3)^3

g(x)=(-27)? is this right?
correction it it should be g(x)=(-30)is this right?
Almost -27 - (-3) = -24
x(x-32)=0
