For f(x) = 2x + 1 and g(x) = x2 - 7, find (f - g)(x). O A. - x2 + 2x + 8
B. - x2 + 2x-6
O c. x2 - 2x - 8
O D. 2x2 – 15

Step-by-step explanation:

f(x)=2x+1

g(x)=2x-7

now,

(f-g)(x)=8

hope it helps.

Option D.

Step-by-step explanation:

The given system of inequalities are

We need to find a solution for the following system of inequalities.

Check each point by these inequalities.

For (-2,-2)

False

So, (-2,-2) is not included in the solution set.

For (1,-5)

False

So, (1,-5) is not included in the solution set.

For (0,0)

False

So, (0,0) is not included in the solution set.

For (5,-2)

True

True

Both inequalities are true for the point (5,-2). So, the point (5,-2) is a solution for the following system of inequalities

Therefore, the correct option is D.
