Question

Solve
If f(x) = 2x² - 3x - 1, find f(x + 2)

Answer 1

please check ypur question i think it should be 2x square-3x+1 find f (x-2)

Answer 2

Answer:

f(x + 2) = 2x² + 5x + 1

Step-by-step explanation:

In the question,

We have been provided

f(x) = 2x² - 3x - 1

So,

We need to find the value of f(x + 2).

So,

On replacing the value of 'x' with (x + 2), we get,

$f(x) = 2x^{2} - 3x - 1\\So,\\f(x+2)=2(x+2)^{2}-3(x+2)-1\\f(x+2)=2(x^{2}+4+4x)-3x-6-1\\f(x+2)=2x^{2}+5x+1$

Therefore, the value of the function f(x + 2) is given by,

f(x + 2) = 2x² + 5x + 1
