Range is the y values or ouputs
domain is inputs or x vvalues
we can use any x value
but at a certain y value, w can't go below that
find thatminimum
find the vertex
for
ax^2+bx+c
the x value of the vertex is
-b/2a
plug that in to the equaiton to get the y value
-b/2a=-(-6)/(2*2)=6/4=3/2
plug that in
2(3/2)^2-6(3/2)-9
2(9/4)-9-9
9/2-18
4.5-18
-13.5
domain=all real numbers
range=from -13.5 to positive infinity
Answer:
Length of kitchen on blueprint = 4 in.
Step-by-step explanation:
Scale used to draw a blueprint of a house :
6 feet = 1 in.
Therefore, 1 feet = 
in.
If the length of kitchen = 24 feet
Then the length of kitchen on the blueprint will be
= 
= 4 in.
Therefore, length of kitchen on blueprint is 4 in.
Answer:
Step-by-step explanation:
y=mx+b
y less than or equal to -3x-23
Answer:
8
Step-by-step explanation:
4^3/2^3
(4^3)/(2^3)
- 4^3 = 64
- 2^3 = 8
64/8 = 8
Answer: B
Step-by-step explanation: I took the quiz and got it right
Also, if you graph the equations on a graphing calculator, the lines are right on top of each other, so the first equation can't be less than -1, so no solutions
