Carly sold 18, Jasmine sold half that. Half of 18 is 9. 9 + 18 = 27.
Together they sold 27 rolls of wrapping paper.
F(x) = a(x - h)³ + k
The parent graph is F(x) = x³
k - shifts the parent graph up k-units (or down if it is negative). This is also called a vertical shift.
h - shifts the parent graph to the right h-units (or left if it is negative). This is also called a horizontal shift.
a - stretches the parent graph vertically by a factor of "a"
Additonally, the coordinate (h, k) is the center/vertex of the graph.
Your answer will turn out to be −4x^2+3x.
A graph shows the appropriate choice to be
A. 277.8 °F
_____
Of course, you get the same result by evaluating
76 + 301*e^(-0.40)
