Question

a funao definida por:
f (x)= x²-7x+10

a) f (0)=
b) f (2)=
c) f (-5)=
d) f (-3)=

Answer 1

f(x)= x²-7x+10

a) f(0) = 0² -7.0 + 10 = 10

b) f(2) = 2² - 7.2 + 10 = 4 - 14 + 10 = 0

c) f(-5) = (-5)² - 7.(-5) + 10 = 25 + 35 + 10 = 70

d) f(-3) = (-3)² - 7.(-3) + 10 = 9 + 21 + 10 = 40



bons estudos :)
