Create the equation of a quadratic polynomial

f(x) = - 3x² - 9x + 30

Step-by-step explanation:

f(x) = ax² + bx + c

a( - 5)² + b( - 5) + c = 0 ⇔ 25a - 5b + c = 0

a(2)² + b(2) + c = 0 ⇔ 4a + 2b + c = 0

(3, - 24)

a(3)² + b(3) + c = - 24 ⇔ 9a + 3b + c = - 24

A = = - 56

= = 168

= = 504

= = - 1680

a = = - 3

b = = - 9

c = = 30

f(x) = - 3x² - 9x + 30

15 batches are the most you can make

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
