Part II: To find the value of a, subtract the y-coordinate of the vertex from the y-coordinate of the point on the parabola that is 1 unit to the right of the vertex.

the least common denominator is 40

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

50-60=10
