Step-by-step explanation:
The parabola that opens up and passes through (-3,-3) will have equation,
The parabola the opens up a d passes through (-3,3) will have equation:
We want to determine the value of k, for which,
We rewrite g(x) in terms of f(x) to get:
Therefore;
Hence k=6
<h3>Answer: Choice C</h3>
=================================================
Explanation:
For choice C, the x values are out of order, so it might be tricky at first. I recommend sorting the x values from smallest to largest to get -2, -1, 0, 1, 2. Do the same for the y values as well. Make sure the correct y values stay with their x value pairs. You should get the list of y values to be 4, 2, 1, 1/2, 1/4
Check out the attached image below for the sorted table I'm referring to
We can see the list of y values is going down as x increases. This is a good sign we have decay. Further proof is that we multiply each term by 1/2 to get the next one
4 times 1/2 = 2
2 times 1/2 = 1
1 times 1/2 = 1/2
1/2 times 1/2 = 1/4
and so on. Effectively we can say the decay rate is 50%
