The slope is undefined, if the line is vertical the slope equation m=(change in y)/(change in x) becomes undefined because youd be dividing by zero
80 I’m sorry if it’s wrong but I’m pretty sure I’m right
You get discontinuity when in this function you divide by 0. You will divide by 0 if x+4 = 0. That means that x = -4
y value for this example doesn't matter because for x = -4 you will have discontinuity. Since the only answer that has -4 as x value is D, that has to be solution.
Answer is D
So,
The range will simply be the absolute value of the difference between the highest and lowest price.
The highest price is $2285.
The lowest price is $1116.
The absolute value of the difference between these two prices is:
|2285 - 1116| = 1169
The range of the prices for the gold phone is $1169.
Answer:

Explanation:
Volume of rectangular prism is same as volume of cuboid
Length = m units
Width = 6m units
Height = 5m units
Volume of rectangular prism = Length × Width × Height
= m × 6m × 5m
= 6m² × 5m
= 30 m³ unit³
