What are the vertex and x-intercepts of the graph of the function below y=(x-4)(x+2)a. vertex: (1,-5); intercepts: x = -4,2b. vertex: (1,-9); intercepts: x = 4,-2c. vertex: (1,9); intercepts: x= -4,-2d. vertex: (-4,2); intercepts: x=3,-3

step-by-step explanation:

abc

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
