Answer 1

`\textsf{(a)} \quad \boxed{9a-3}`

`\textsf{(b)} \quad \boxed{-9a-3}`

`\textsf{(c)} \quad \boxed{-9a+3}`

Explanation:

Given function:

`f(x) = 9x - 3`

Part (a)

To find f(a), substitute x = a into the function:

`\implies f(a)=9a-3`

Part (b)

To find f(-a), substitute x = -a into the function:

`\implies f(-a)=-9a-3`

Part (c)

To find -f(a), first substitute x = a into the function:

`\implies f(a)=9a-3`

Then make the function negative:

`\begin{aligned}\implies -f(a)&=-(9a-3)\\&=-9a+3 \end{aligned}`

Answer 2

Given function

• f(x) = 9x - 3

Find the following

• a) f(a) = 9a - 3
• b) f(-a) = 9(-a) - 3 = - 9a - 3
• c) - f(a) = - (9a - 3) = - 9a + 3
