Which function has zeros at x = -2 and x = 5?
f(x) = x2 + 2x - 10
f(x) = x2 - 2x - 10
f(x) = x2 + 3x - 10
f(x) = x2 - 3x - 10
Solution:
Given zeros at x = -2, x = 5
Factored form is (x + 2)(x - 5)
Using the distributive property, we mutliply these factors.
x2 - 5x + 2x - 10
x2 - 3x - 10
f(x) = x2 - 3x - 10
Therefore, the function f(x) = x2 - 3x - 10 has zeroes at x = -2 and x = 5
Which function has zeros at x = -2 and x = 5?
Summary:
The f(x) = x2 - 3x - 10 function has zeros at x = -2 and x = 5.
