Let f(x)=3x-5 and g(x)=4-x^2. Evaluate each expression symbolically. (a) (f+g)(3) (b) (f-g)(- 2) (c) (fg)(1) (d) (StartFraction f Over g EndFraction )(5)

a) -1

b) -11

c) -6

d) -10/21

Step-by-step explanation:

We have that

So

(a) (f+g)(3)

We replace x by 3. So

(b) (f-g)(- 2)

We replace x by -2. So

(c) (fg)(1)

We replace x by 1. So

(d) (f/g)(5)

We replace x by 5. So

step-by-step explanation:

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)
