Write an equation of a parabola with x-intercepts at (1/4,0) and (-7,0) which passes through the point (0,7).

f(x) = - 4x² - 27x + 7

Step-by-step explanation:

f(x) = a*(x-1/4)(x+7) = a(x² + 27/4 x - 7/4)

pass (0,7):   7 = a (-7/4)

a = -4

f(x) = -4*(x² + 27/4 x - 7/4)

f(x) = -4x² - 27x + 7

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.

you bought 31 v bucks

step-by-step explanation:

25+6=31
