Answer:
B
Step-by-step explanation:
Because it can be a a negative number
it doesn't have to be greater than 0
Hope I help
Hi there!
The vertex form equation is y=a(x-d)^2+c where the vertex is (d, c).
The vertex is always the turning point when the y-values start to travel in the opposite direction from which they began traveling on the opposite side of the turning point. Therefore the point (4, -4) is the vertex.
y=a(x-4)^2-4
We can sub in a point on the graph in order to solve for the a-value. Let's use (6, 0), and sub that in for x and y.
0=a(6-4)^2-4
0=a(2)^2-4
4=4a
a=4/4
a=1
Therefore the equation is y=(x-4)^2-4
Hope this helps!
Answer: (3, 6)
Step-by-step explanation:
1. You have the following function:
2. To find the point that lies on the graph of the function above, you can substitute the value of <em>x</em> given in the option; if you obtain the value of <em>y</em> shown in that option, then that point lies on the graph. Then, you have:
3. The point is (3,6), then it is lie on the graph.
It would take them 12 minutes to finish 1 mile.
60 minutes/5 miles= 12 minutes
