Can someone help me now plz and thank you :)
f(x) = 0.25x2 − 8x + 600
The following table represents the production cost g(x), in dollars, for x number of units produced by company 2:
xg(x)
6862.2
8856.8
10855
12856.8
14862.2
Based on the given information, determine which company has a lower minimum and find the minimum value.
g(x) at (10, 855)
f(x) at (16, 536)
g(x) at (16, 536)
f(x) at (10, 855)
2 A quadratic equation is shown:
x2 − 14x + 41 = 0
Which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers?
x2 − 14x + 41 + 8 = 0 + 8
x2 − 14x + 41 + 9 = 0 + 9
x2 − 14x + 41 − 8 = 0 − 8
x2 − 14x + 41 − 9 = 0 − 9
3 An icicle drips at a rate that can be represented by the function f(x) = −x2 + 9x − 18, where 0 ≤ x ≤ 10 and x is the number of hours after the sun has risen. When f(x) is a negative number, the icicle is not dripping. Determine the values when the icicle starts and stops dripping.
x = −3 and x = 6
x = 3 and x = −6
x = 3 and x = 6
x = −3 and x = −6
