Liono4ka [1.6K]

Answer: 348

Step-by-step explanation:

Given : Total employees work = 725

Find a quadratic function that includes the set of values below.<br> (0,9). (2,15) (3,12)
nlexa [21]

Answer:

f(x) = -2x^2 + 7x + 9

Step-by-step explanation:

f(x) = ax^2 + bx + c\\f(0) = 9 => c = 9;\\f(2) = 15 = 4a + 2b + 9  2a + b  = 3\\f(3) = 9a + 3b + 9 = 12  3a + b = 1\\Subtract the second equation from the first:\\-a = 2 => a = -2; b = 7; c = 9\\f(x) = -2x^2 + 7x + 9
