Question

1. Let f(x) = 2x^+x-3 and g(x) = x-1 preform the indicated operation, then find the domain.

Answer 1

Step-by-step explanation:

#1

• $f(x) = 2x^2 + x - 3$
• $g(x) = x - 1$

<u />$\text{Find (f - g)(x):}$

• $(f - g)(x) = f(x) - g(x) = 2x^2 + x - 3 - x + 1 = 2x^2 - 2$

Correct choice is D

• <em />$\text{The rest of the parts are confusing since f(x) and g(x) are same as in the first part}$
