Question

Which of the following statements have the same result? Explain each step in solving each one.

f(3) when f(x) = 2x + 2
f-1(4) when f(x) = 3x minus 4, all over 5
y + 10 = 2y + 1

Answer 1

Answer 2

f(3) when f(x)=2x+2
f=2(3)+2
f=5+2
f=7

Answer 3

f(4) when f(x)=(3x-5)/4
f=(3*4-5)/4
f=(12-5)/4
f=7/4
f=1.75

Answer 4

Thanks :3

Answer 5

y+10=2y+1
-1 -1
y+9=2y
-y -y
9=y

Answer 6

The other one, i'm not sure because you put f-1(4)

Answer 7

No prob :)
