Y = 0.4x^2 + 2x + 2.5 Help!

Step-by-step explanation:

Are you trying to find the x-intercepts?

Pythagorean Theorem:

x = [-2 ±√(2^2-4(0.4)(2.5)]/[2(0.4)] = -2.5

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

ou would have 12 of each
