Question

Can anyone help me on this?

Answer 1

Answer is :

• -x² + 2x - 6

Step-by-step Step-by-step explanation:

Here,

f(x) = 2x + 1

g(x) = x² - 7

We have to find (f - g) (x)

(f - g) (x) is similar to f(x) - g(x)

Further solving for f(x) - g(x)

Put value of f(x) and g(x) here

2x + 1 - x² - 7

2x - x² - 6

-x² + 2x - 6

Similarly, (f - g) (x) = -x² + 2x - 6 (Answer)
