Question 983283: Consider the function Y = x2 � 2x � 15 and determine the followings:
a. Slope of the function.
b. The intercept.
c. Whether the function has a minimum or a maximum
d. Minimum or a maximum value of the graph

The attempted function being express looks like , and this does not have a slope, because a slope relies on any two points. Slope is for a LINE. Your function may be a parabola (or so it seems as expressed).

Your function has a minimum. Put into standard form and read the vertex( a minimum point) from the equation. You also can find x-intercepts from the standard form equation.

y-intercept:

-----------the point (0,-15)

Transform into standard form:

-----------Now find the minimum point and any x-intercepts from this standard form equation.
