The general vertex form is this:
v(x) = a (x-h)2 + k
where (h,k) is the coordinates of the of vertex.
and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.
Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:
The graph is reflected over the x-axis
The graph is made narrower.
The graph is shifted 6 units to the left.
The graph is shifted 48 units up.
From the choices we only have:
<span>The graph of f(x) = x2 is made narrower</span>
The answer is c=50.272, for other problems like this use the formula: The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle).
Answer:
$6083.26
Step-by-step explanation:
100+4 = 104
104/100 = 1.04
5000 * 1.04^5 = 6083.264512
Answer:
9x^9-18
Step-by-step explanation:
Answer:
12,464 ft
Step-by-step explanation:
I assume that the elevation of the lake is the altitude at the surface of the water.
The surface of the lake is 922 ft above the deepest point of the lake.
11,542 ft + 922 ft = 12,464 ft
