Given that f(x) = x2 - 2x - 15, a. Find the coordinates of the y-intercept

b. Find the coordinates of the x-intercepts

c. Find the coordinates of the vertex

d. Use the above information to sketch a graph of f(x)

a) (0; -15)

you just let x be equal to 0.

b) ( -5; 0) and (3;0)

you just let y/ f(x) equal to 0.

c)

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
