1.) f(-2) = (-2)⁴ - 4(-2)³ + 3(-2)² - 5(-2) - 1
f(-2) = (16) - 4(-8) + 3(4) + 10 - 1
f(-2) = (16) + 32 + 12 + 9
f(-2) = 69
2. f(x) = 3x + 2x + 10
f(1) = 3(1) + 2(1) + 10
f(1) = 3 + 2 + 10
f(1) = 15
3. f(x) = x³ - 7x² + 9x
f(-3) = (-3)³ - 7(-3)² + 9(-3)
f(-3) = -81 - 7(9) - 27
f(-3) = -81 - 63 - 27
f(-3) = 171
4. f(x) = x - 3x² + x - 5
f(3) = 3 - 3(3)² + 3 - 5
f(3) = 3 - 3(3)² + 3 - 5
f(3) = 3 - 3(9) - 2
f(3) = 3 - 27 - 2
f(3) = - 26
5. f(x) = 4x³ - 4x + 5x² + x
f(3) = 4(3)³ - 4(3) + 5(3)² + 3
f(3) = 4(27) -12 + 5(9) + 3
f(3) = 108 - 12 + 45 + 3
f(3) = 144
