Question

dadas las siguientes funciones:
f(x)= 2x–1
g(x)=x²–x+2
calcular

f(1)+g(2)=
f(–1)–g(3)=

gracias!!:(​

Answer 1

1.

f(1) = 2(1) - 1 = 1

g(2) = (2)^2 - 2 + 2 = 4

f(1) + g(2) = 1 + 4 = 5

2.

f(-1) = 2(-1) - 1 = -2 - 1 = -3

g(3) = 3^2 - 3 + 2 = 9 - 3 + 2 = 8

f(-1) - g(3) = -3 - 8 = -11
