SOLUTION: Hi I would like some help in solving to find the x and y intercepts of the equation: y=x^2-6x+8 For the Y-intercept I was able to get that y=8 but I am not sure if that is right

Question 783408: Hi I would like some help in solving to find the x and y intercepts of the equation: y=x^2-6x+8
For the Y-intercept I was able to get that y=8 but I am not sure if that is right and I cant solve for x. If you could help me that would be greatly appreciated.

No. Your

-intercept is not right. An intercept is a point. A point in

is designated by an ordered pair. The number 8 is not an ordered pair. The

-coordinate of the

-intercept is, indeed, 8. The

-coordinate of any

-intercept is zero. Hence your

-intercept is the point

.

To find the

-intercepts, first find the zeros of the quadratic function. In other words, set the function equal to zero and solve by any convenient means. Hint: this one factors over the integers. Note that -2 times -4 = 8 and -2 plus -4 = -6. Once you have the two zeros of the function,

and

, you can form the ordered pairs that represent the two

-intercepts thus:
