Question

F(a)=-2a-4
g(a) =a^ 2+3
Find (f/g)(7)

Answer 1

`(f/g)(7)=-(9)/(26)`.

Explanation:

1. Write the expressions.

`f(a)=-2a-4\\ \\g(a) =a^ 2+3`

2. Since we need to find f/g, we take the arguments of both f(a) and g(a) and divide them.

`(-2a-4)/(a^ 2+3)`

3. Evaluate the expression by the indicated number.

For this, we substitute a by 7 throughout the entire expression and calculate.

`f/g(7)=(-2(7)-4)/((7)^ 2+3)=(-18)/(52) =-(9)/(26)`

4. Express your result.

`(f/g)(7)=-(9)/(26)`.
