Question

what are the vertex and x intercepts of the graph of y= x^2-2x-24

Answer 1

Answer:

vertex : (1, -25)   x-intercepts:   x = 6 , x = -4

Step-by-step explanation:

y =  x^2 - 2x - 24

rewriting this in vertex form:

y = xx - 2x + 1  - 1 - 24

y = (x - 1)^2  - 25

vertex is at  (1, -25)  

intercepts...

0 =  (x - 1)^2  - 25

5 = x - 1

or - 5 = x - 1

x = 6 or   x = -4
