Answer 1

@HawkCrimson

Answer 2

any ideas?

Answer 3

no clue

Answer 4

think of the graph, wat is the y value when any pt is on the x-axis?

Answer 5

0

Answer 6

yep so when the graph crosses the x-axis the equation is 0 = 2x^2 + x − 15 cause y = 0

Answer 7

ok..

Answer 8

what do i have to do next? @HawkCrimson

Answer 9

solve for x and then state the two points where the curve cuts the x-axis

Answer 10

0 = (x + 3)(2x - 5)

Answer 11

great so wat r the two coordinates where the graph cuts the x axis?

Answer 12

-3 and 5/2

Answer 13

D

Answer 14

well u didnt give the choice of answers so i cannt confirm it :/ but yea the points r (-3,0) and (5/2, 0)
