What are the x– and y–intercepts of the graph of y = x2 – 10x + 21?
a. x–intercepts: (–3, 0) and (–7, 0)
y–intercept: (0, –21)
b. x–intercepts: (–3, 0) and (–7, 0)
y–intercept: (0, 21)
c. x–intercepts: (7, 0) and (3, 0)
y–intercept: (0, 21)
d. x–intercepts: (3, 0) and (7, 0)
y–intercept: (0, –21)
Update:y = x2 – 10x + 21
the x2 is x squared

Verified answer
if we take x=0 and put in the equation we get y intercept so y=21
if we take y= we get x intercept.if we solve x2 – 10x + 21=0 we get x1=7 and x=3
so the answer can be:
y intercept:(0,21)
x intercept (3,0) and (7,0)
the answer is c
It's c :)
