Question

f(4) if f(x)=x^2-3x+3

Answer 1

this kind of question basically ask you to calculate the value of the equation f with a value given of x.
In this case, it is f(4)=4^2-3*4+3=16-12+3=7.
Just put 4 in x's place and you are good to go :)

Answer 3

what about \[g(x)=2x-1 if g(3)

Answer 4

you do the same thing, put 3 to where x is
in this case, g(3)=2*3-1=6-1=5
