What are the x- and y-intercepts of the graph of y = x2 − 10x + 21?

y intercepts: y = 21

x intercepts: x = 3 and x = 7

Step-by-step explanation:

The given graph is y = x² - 10x + 21

We have to find the x and y intercepts of the given graph.

Since we know for x- intercepts we equate y = 0 and for y-intercepts we put x = 0

Now for x-intercepts

x² - 10x + 21 = 0

x² - 7x - 3x + 21 = 0

x(x - 7) - 3(x - 7) = 0

(x - 3)(x - 7) = 0

x - 7 = 0

x = 7

Or x - 3 = 0

x = 3

Therefore, there are two x intercepts x = 3 and x = 7

Now for y-intercepts

y = 0 - 0 + 21

y = 21

Therefore, x intercepts are; x = 3 and x = 7 and y intercept is y = 21

answer: the answer is 35%

its 4 because 2 times 2 is 4, if you double the number two you get four
