Answer:
C- (14, 4); The vertex represents the maximum profit.
Step-by-step explanation:
The leading coefficient of the quadratic function is negative, so the graph opens downward, and the vertex represents a maximum.
The maximum value is at ...
x = -b/(2a) = -28/(2(-1)) = 14
f(14) = -14^2 +28(14) -192 = 4
The vertex is (14, 4). It represents the maximum profit.
2 more because 5 is 5-3 = 2 so the answer is 5/2
Answer:
-3 comes from combining 1 and -4
Step-by-step explanation:
The -3 under the radical is the result of combining the terms
16 -4(16) = 16(1 -4) = 16(-3) = -3(16)
16 is factored out. It is done this way because 16 is a perfect square factor, so wants to maintain that identity while you figure out the rest of the radical.

Like terms are terms that are the exact same excluding coefficients.
To combine like terms, add or subtract the coefficients.
Here are a few examples.
-3x^2+ 2x^2= -x^2
14xyz-12xyz=2xyz
12p-3p+8p= 17p
