The function g(x) = x³ - x² - 4x + 4 has zeros at 1, 2 and -2. The y intercept is at 4.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
The zeros of the function is at:
g(x) = 0, hence:
x³ - x² - 4x + 4 = 0
(x - 1)(x² - 4) = 0
(x - 1)(x + 2)(x - 2) = 0
x = 1, x = -2 and x = 2
The y intercept is at x = 0, hence:
g(0) = 0³ - 0² - 4(0) + 4 = 4
The function g(x) = x³ - x² - 4x + 4 has zeros at 1, 2 and -2. The y intercept is at 4.
