Question

math problem

Answer 1

Very similar to last time

what are the x-intercepts? where does it cross the x-axis

Answer 2

1 4

Answer 3

so how would you write that if x = 1 and x = 4

Answer 4

(x+1)(x+4)

Answer 5

No, you got it switched again

x = 1
x - 1 =1 - 1
x -1 = 0

(x-1) would be one of the factors of the equation

what about if x = 4

Answer 6

oof already answered

Answer 7

(x-1) (x-4)

Answer 10

yes so we have

y = a(x-1)(x-4)

and we need to find out what 'a' is

and on your graph, you see the point (0, -4) so plug that in

-4 = a(0-1)(0-4)

what is 0 - 1 =
what is 0 - 4 =

Answer 11

-1 -4

Answer 12

yes so we have

-4 = a * -1 * -4

what is -1 * -4 = ??

and then solve for a

Answer 13

a=-1

Answer 14

exactly so now we have

y = -1(x-1)(x-4)

can you simplify that?

Answer 15

-x^2+5x-4
