The right answer is C
Let me to explain. From the graph we know that the vertex of this parabola is 
. This is a<em> maximum y-value.</em> We also know that the parabola <em>opens downward, </em>so the leading coefficient is negative. Given that the function is even and the leading coefficient is negative, it follows that the graph falls to the left and right. In a mathematical language this is:
<em> </em>

Answer:
Step-by-step explanation:
m is number of miles
A: 45+0.21m (45 is the initial cost)
B: 28+0.38m (28 is the initial cost)
To know how in many miles the cost will be equal,
45+0.21m=28+0.38m
0.38m-0.21m=45-28
0.17m=17
m=17/0.17 = 100
So, at 100 miles the cost will be same for company A and B.
