The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).
<h3>What is the parabola?</h3>
It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The function f(x) = 5x² + 40x
Then add and subtract 80, then we have
f(x) = 5x² + 40x + 80 – 80
f(x) = 5(x² + 8x + 16) – 80
f(x) = 5(x + 4)² – 80
The vertex of the parabola will be at (–4, –80).

The correct answer would be : True
I hope that this helps you !
You plot the points of GYTD on the coordinate plane and then you move 2 units left and 2 units up and you then look where the points ended up and that's you answer
Your answer is C, 5 to 9.
So, the interval 3.1 ≤ x ≤ 7.0 is actually between one standard deviation below the mean and 2 standard deviations above the mean. In normally distributed data, about 34 % of the values lie between the mean and one standard deviation below the mean, and 34 % between the mean and one standard deviation above the mean.
