Answer 1

\(f(\color{red}{x})=\color{red}{x}^2 +2\)
Now \(f(\color{blue}{x^2})= ...+2\)
Can you fill it up?

Answer 2

2x^2 ? @Loser66

Answer 3

What would the steps be to find that out?

Answer 4

ok, go steps!!
if f(x) = x , then f(y) =?

Answer 5

y

Answer 6

@Loser66

Answer 7

yeah, now f(z) =?

Answer 8

z

Answer 9

ok, a litlle bit harder
if f(x) =x+2, then f(y) =?

Answer 10

y = y + 2

Answer 11

f(y) = y+2, not y = y+2, ok?

Answer 12

Is is x^2 + 4?

Answer 13

and okay

Answer 14

so, if I say, if f(x) = x^2 +2, then , f(y) = ?

Answer 15

f(y) = y^2 + 2

Answer 16

yup yup yup
