Question

F(x)=2/3x-5
find f(-3/4)

Answer 1

-5.5

Explanation:

To find f(-3/4) we substitute the values and solve the function:

`f(x)=(2)/(3)x-5`
Substitute:

`f(-(3)/(4))=(2)/(3)( -(3)/(4))-5`
Solve while making sure to simplify:

`(2)/(3) *-(3)/(4) =(-6)/(-12) /3=(-2)/(-4) /2=-(1)/(2)`

`-0.5-5=-5.5`

`f=-5.5`

Depending of course on which form is needed for the answer, -5.5 is its decimal form.

I hope this helps.
