sorry, last one i swear!
please help, thankyou all!
Find the points of intersection between the porabola and line:
y = x^2 + 12x + 24
y = 4x + 9
!!
i thought i had more brain cells than that!
Hello, georgiaaa!
Find the points of intersection of the parabola and line:
. . y .= .x² + 12x + 24
. . y .= .4x + 9
To find the intersection of two curves, equate the functions.
. . x² + 12x + 24 .= .4x + 9
. . . x² + 8x + 15 .= .0
. . (x + 3)(x + 5) .= .0
And we have: .x = -3, -5
The corresponding values are: .y = -3, -11
Therefore, the intersections are: .(-3,-3) and (-5,-11)
