Question

If f(x) = x2-
X, what is f (-3)?

Answer 1

`\sf \: f( - 3) = 12`

Explanation:

Now we have to,

→ Find the required value of f(-3).

The function is,

→ f(x) = x² - x

Then the value of f(-3) will be,

→ f(x) = x² - x

→ f(-3) = (-3)² - (-3)

→ f(-3) = (-3)² + 3

→ f(-3) = 9 + 3

→ [ f(-3) = 12 ]

Hence, the value of f(-3) is 12.
