Question

The graph of f(x) = 3x² -5x-22 passes through the point (0-22) and one of its zeros is -2. What is the other zero of the function?​

Answer 1

Answer:
`(11)/(3)`, or 3
`(2)/(3)` or 3.67

Explanation:

`3x^2-5x-22`

1. Factor

`(3x-11)(x+2)`

2. Set each expression in parenthesis equal to 0

`3x-11 = 0, x+2 = 0`

3. Solve for X

`x = (11)/(3) , x = -2`

4. Since we are given -2 as a solution, the other zero of the function is
`(11)/(3)`, or 3
`(2)/(3)`
