Question

Consider the graph of a quadratic function shown to the right.
A. Write a quadratic function that has x^2 -coefficient equal to 1 and has the x-intercepts indicated.
B. Write a quadratic equation in the variable x, with X^2 -coefficienent equal to 1, that has solutions of -6 and -2
c. How many different quadratic functions can have x intercepts of -6 and -2?
D. How many different quadratic equations in one variable can have solutions of -6, and -2?

Answer 1

@Agent47

Answer 2

The graph is a u shape and crosses on the x-axes at both -2, and -6.

Answer 3

@Agent47

Answer 4

can u tell me at what y-value is its lowest point?

Answer 5

-4 is it's lowest point on the y axis

Answer 6

brb gonna make some tea..

Answer 7

ok

Answer 8

A. Write a quadratic function that has x^2 - coefficient equal to 1 and has the x-intercepts indicate:
y=x^2+bx+c
0
Intercepts are -6 and -4, so:
0=(-6)^2+b(-6)+c
0=(-2)^2+b(-2)+c

-36=-6b+c
-4=-2b+c

Answer 9

ok so that is going to be my A part for my formula?

Answer 10

A: y=x^2+8x+14

Answer 11

wait let me check it

Answer 12

ok

Answer 13

y=x^2+8x+12

Answer 14

ok im back my computer knocked me off

Answer 15

sorry i froze when i was typing that 14 shld be 12

Answer 16

yeah Marina's right

Answer 17

so it's x^2+8x+12?

Answer 18

For a part

Answer 19

yea for A

Answer 20

ok

Answer 21

B is the same thing

Answer 22

same answer?

Answer 23

yea

Answer 24

for the next one it says ___different quadratic functions or infintiy

Answer 25

c. How many different quadratic functions can have x intercepts of -6 and -2?
infintely many

Answer 26

infinity

Answer 27

Is D going to be infinity also?

Answer 28

D. How many different quadratic equations in one variable can have solutions of -6, and -2? yea it shld be infinity as well

Answer 29

Great!!! Thanks alot :)
