Answer 1

Respuesta:

:)

Explicación paso a paso:

Si f(x) =-3x +4.

Hallar f(3)-f(-2) +f(5)

f(x) =-3x + 4

f(3) =-3(3) + 4

f(3) =-9 + 4

f(3) =-5

f(x) =-3x + 4

f(-2) =-3(-2) + 4

f(-2) = 6 + 4

f(-2) = 10

f(x) =-3x + 4

f(5) =-3(5) + 4

f(5) =-15 + 4

f(5) =-11

f(3)-f(-2) +f(5) = x

-5 + 10 - 11 = x

-16 + 10 = x

x = -6
