Question

What are the x– and y–intercepts of the graph of y = x2 – 10x + 21

can anyone run me through how to find both the x and y?

Answer 1

put x=0 and solve for y, thats the y-intercept and same is x-intercept (put y=0)

Answer 2

hmm okay so y equals 21
y- intercepts are (0,21)

then x= 3,7
so on a graph x intercepts are (3,0) (7,0)

Answer 3

yup

Answer 4

now plot these points and join with a smooth curve u get the graph

Answer 5

okay thanks for your help!!

Answer 6

pleasure
