Step-by-step explanation:
In order to convert kilometers to miles, we can use a formula, assuming is miles and
is kilometers.
.
Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.
Hope this helped!
The trick here is to substitute points given
substituting point A x-value =b
turns out false since (b,a*b^b) !=(b,0)
substituting point B x-value=0
turns out true since (0,a)=(0,a)
we already got f(x) at x =0 which is not the point (0,0)
so c is false
substituting D x-value=a
hence B is the correct answers
