Question

Help

Answer 1

for part I it is asking for the y-intercept so simply set x = 0 and solve for y

Answer 2

y=-14

Answer 3

awesome

for part B, identify the a, b, and c values of the function

then find x = -b/(2a)

Answer 4

a=1
b=-5
c=-14

Answer 5

awesome, then x = -b/(2a) = ?

Answer 6

5/2

Answer 7

good, so that's the x-coordinate of the vertex

to find the y-coordinate plug x = (5/2) into the function y = x^2 - 5x - 14

Answer 8

y=-81/4

Answer 9

awesome

for part C simply factor y = x^2 - 5x - 14

Answer 10

y=(x-7)(x+2)

Answer 11

good, so the x-intercepts are 7 and -2

in (x,y) form these are (7,0) and (-2,0)

that's it for part c

Answer 12

okay thanks
