Question

calcule os valores indicados das funções abaixo:
a) g(x)=5x+1;g(-1), g(1), g(1), g(2)

b) h(t)=t²+2t+4; h(2), h(0),h(-4)

c) g(x)=(X+1)²; g(0), g(-1),g(8)

Answer 1

a) g(x)=5x+1
g(-1)=5.(-1)+1
g(-1)=-5+1
g(-1)=-4
g(1)=5.1+1
g(1)=5+1
g(1)=6
g(2)=5.2+1
g(2)=10+1
g(2)=11
b) h(t)= t^2+2t+4
h(2)=2^2+2.2+4
h(2)=4+4+4
h(2)=12
h(0)=0^2+2.0+4
h(0)=0+0+4
h(0)=4
h(-4)=(-4)^2+2.(-4)+4
h(-4)=16-8+4
h(-4)=16-4
h(-4)=12
c) g(x)= (x+1)^2
g(0)=(0+1)^2
g(0)=0+1
g(0)=1
g(-1)=(-1+1)^2
g(-1)=1+1
g(-1)=2
g(8)=(8+1)^2
g(8)=64+1
g(8)=65
