Answer 1

Respuesta:

a + b = 0

Explicación paso a paso:

g(x) = 7x - 3

g(h) = 7h - 3

g(h) - 2 = f(h)

7h - 3 - 2 = f(h)

7h - 5 = f(h)

f(h) = 7h - 5

f(a) = - 19

f(a) = 7a - 5

7a - 5 = - 19

7a = - 19 + 5

7a = - 14

a = - 2

f(1) = b

f(1) = 7(1) - 5

f(1) = 7 - 5

f(1) = 2

b = 2

a + b = - 2 + 2

a + b = 0
