Question

Solve the problem below

Answer 1

(f+g)(0)=

f+g= -3x+x-7 = -2x-7

(f+g)(0)= -2*0 -7 =-7

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

(f-g)(5)= -2*10 + 7= -13

Explanation:

Answer 2

- 7 and - 13

Explanation:

(f + g)(0)

= f(0) + g(0)

= - 3(0) + 0 - 7

= 0 + 0 - 7

= - 7

---------------------------

(f - g)(5)

= f(5) - g(5)

= - 3(5) - (5 - 7)

= - 15 - (- 2)

= - 15 + 2

= - 13
