ANSWER:
Given f(x) = –x3 – 3x2 – 3x + 3, find f(–1), f(0), and f(3)
ANSWER:
Given f(x) = –x^3 – 3x^2 – 3x + 3,
To find f(–1), f(0), and f(3).....replace x by -1, 0 and 3 in the given equation.
f(x) = –x^3 – 3x^2 – 3x + 3,
f(-1) = –(-1)^3 – 3(-1)^2 – 3(-1) + 3
==> = -(-1) + 3 + 3 + 3
==> = 1 + 3 + 3 + 3
==> f(-1) = 10
f(0) = –(0)^3 – 3(0)^2 – 3(0) + 3
==> = -0 -0 -0 + 3
f(0) = 3
f(3) = –3^3 – 3* 3^2 – 3*3 + 3
==> = -27 - 3 * 9 - 9 + 3
==> = -27 -27 - 9 + 3
==> = -63 + 3
==> = -60
Hope you found the method useful.
