Question

If f(x) = 2x2 – 2, what is
X, what is f(-6)
give the right answer for a brilliant!

Answer 1

f(- 6) = 70

Explanation:

To evaluate f(- 6) , substitute x = - 6 into f(x)

f(- 6) = 2(- 6)² - 2 = 2(36) - 2 = 72 - 2 = 70

Answer 2

`\sf \: f( - 6) = 70`

Explanation:

Given function,

→ f(x) = 2x² - 2

Now we have to,

→ Find the required value of f(-6).

Then the value of f(-6) will be,

→ f(x) = 2x² - 2

→ f(-6) = 2(-6)² - 2

→ f(-6) = 2(36) - 2

→ f(-6) = 72 - 2

→ [ f(-6) = 70 ]

Hence, the value of f(-6) is 70.
