I need the answer in the next hour please!


f(x)=2(x)^2-2, Find f(2-a)


f(2-a)=2(2-a)^2-2

Answer 1

Answer:

• 2a² - 8a + 6

Step-by-step explanation:

Given function:

• f(x) = 2x² - 2

To find f(2 - a) substitute x with 2 - a:

• f(2 - a) =
• 2(2 - a)² - 2 =
• 2(4 - 4a + a²) - 2 =
• 2a² - 8a + 8 - 2 =
• 2a² - 8a + 6

Answer 2

f(x)=2(x)^2-2

$\\ \rm\hookrightarrow f(2-a)$

$\\ \rm\hookrightarrow 2(2-a)^2-2$

$\\ \rm\hookrightarrow 2(2^2-4a+a^2)-2$

$\\ \rm\hookrightarrow 2(4-4a+a^2)-2$

$\\ \rm\hookrightarrow 8-8a+2a^2-2$

$\\ \rm\hookrightarrow 2a^2-8a+6$
