Answer:
a) 3
b) 39
c) - 27
Step-by-step explanation:
a) f(x) = 5x2 - 6x + 7
f(0) = (5x2) - (6(0) + 7)
f(0) = 10 - (0 + 7)
f(0) = 10 - 7
f(0) = 3
b) f(x) = 5x2 - 6x + 7
f(-6) = (5x2) - (6(-6) + 7)
f(-6) = 10 - (-36 + 7)
f(-6) = 10 - (-29)
f(-6) = 10 +29 = 39
c) f(x) = 5x2 - 6x + 7
f(5) = (5x2) - (6(5) + 7)
f(5) = 10 - (30 + 7)
f(5) = 10 - 37
f(5) = - 27
