Question

what are the x– and y–intercepts of the graph of y = x^2 – 10x + 21?

x–intercepts: (–3, 0) and (–7, 0)
y–intercept: (0, –21)

x–intercepts: (7, 0) and (3, 0)
y–intercept: (0, 21)

x–intercepts: (3, 0) and (7, 0)
y–intercept: (0, –21)

x–intercepts: (–3, 0) and (–7, 0)
y–intercept: (0, 21)

Answer 1

use the quadratic formula :)

Answer 2

Need not to use that..

Answer 3

For x intercept put y =0

and then use factorization..

For y intercept: put x = 0

Answer 4

or you can factor

(x-3)*(x-7)

3 and 7

Answer 5

its c

Answer 6

-------------------------->

Answer 7

3 and 7 for x intercepts

Answer 8

No it is not..

Answer 9

b****

Answer 10

its B

Answer 11

guessing only..

Answer 12

becoz y intercept =(0,21)

Answer 13

i said that

Answer 14

Yeah It is B..

Answer 15

3 and 7 are x intercepts

in other wordds

(3,0) and (7,0)
:)

for y just set x to zero
