Question

If f(x)=ax^3+bx^2+cx+d find f(1), f(2), f(3), f(4), f(5), f(6)

Answer 1

f(1) = a + b + c + d

f(2) = 8a + 4b + 2c + d

f(3) = 27a + 9b + 3c + d

f(4) = 64a + 16b + 4c + d

f(5) = 125a + 25b + 5c + d

f(6) = 216a + 36b + 6c + d

Explanation:

For these problems, subsititue the number in the x position in f(x) in for the x in the equation.

For example for f(2)

f(2) =
`a(2)^(3) + b(2)^(2) + c(2) + d`

f(2) = 8a + 4b + 2c + d
