Question

If f(x) = 3x2 - 3x – 2, then f(-2) =

Answer 1

`\sf \: f( - 2) = 16`

Explanation:

Given function,

→ f(x) = 3x² - 3x - 2

Now we have to,

→ Find the required value of f(-2).

Then the value of f(-2) will be,

→ f(x) = 3x² - 3x - 2

→ f(-2) = 3(-2)² - 3(-2) - 2

→ f(-2) = 3(4) - (-6) - 2

→ f(-2) = 12 + 6 - 2

→ f(-2) = 12 + 4

→ [ f(-2) = 16 ]

Hence, the value of f(-2) is 16.
