Question

Dada a função f(x) = -2x + 10, determine

f(-3)
f(0)
f(4)
f(5)
f(8)
f(9/2)
f(-7/2)

​

Answer 1

Explicação passo-a-passo:

f(x)= - 2x +10

f(-3)= -2.(-3) +10= +6+10= 16

f(0)= -2.0 +10 =+ 10

f(4)= -2.4+10= - 8 +10= +2

f(5)= - 2.5 +10= -10+10=0

f(8)= -2.8 +10 = -16 +10= - 6

f(9/2)= -2.(9/2) +10= -9+10= +1

f(-7/2)= - 2(-7/2)+10= +7+10=17
