Question

Dada a função f (x) = 8 x + 15,calcule:
.a)f(0)-f(3)=
b)f(5)-f(10)=
c)f(7)+f(-3)=
d)f(2)+f(3)=

Answer 1

a) f(0)-f (3)=8(3)+15=15+15-24+15=21
b) f(5) -f (10)=8(10)+15=40+15-80+15=-10
c)f(7)+f(-3)=8(7)+15+8(-3)+15=56+15-24+15=62
d) f(2)+f(3)=8(2)+15+8(3)+15=16+15-24+15=22

Answer 2

a) f(0)-f (3)=8(3)+15=15+15-24+15=21
b) f(5) -f (10)=8(10)+15=40+15-80+15=-10
c)f(7)+f(-3)=8(7)+15+8(-3)+15=56+15-24+15=62
d) f(2)+f(3)=8(2)+15+8(3)+15=16+15-24+15=22
