Question

F(x)=2x^2+3 and g(x)=x^2-7 find (f-g)(x)

Answer 1

Answer:

$(f-g)(x)=x^2+10$

C is the correct option.

Step-by-step explanation:

We have been given that

$f(x)=2x^2+3\\\\g(x)=x^2-7$

The function (f-g)(x) can rewritten as

$(f-g)(x)=f(x)-g(x)$

Substituting the value of f(x) and g(x)

$(f-g)(x)=2x^2+3-(x^2-7)$

Distribute negative over the parenthesis

$(f-g)(x)=2x^2+3-x^2+7$

Now, combine the like terms

$(f-g)(x)=x^2+10$

C is the correct option.
