Question

Please help me, I'm struggling with this question

Answer 1

$\underline{\boxed{\tt{\red{\:Solution}}}}$

Given:-

• f(x) = x²

Evaluation:-

e).

==> f(x) = x²

So,

==> f(3x) = (3x)² = 9x²

f).

==> f(x/2) = (x/2)² = x²/4

g).

==> 3f(x) = 3x²

h).

==> 2f(x-1)+5 = 2(x-1)²+5 = 2(x² + 1 - 2x ) + 5

= 5x² + 5 - 10x + 5

= 5x² - 10x + 10
