f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
Answer:
8. 0
9. undefined
Step-by-step explanation:
8. 0
> because the y variable is the same for all x-values, this is a horizontal line. Horizontal lines have a slope of 0.
> <em>Thinking of slope as rise over run: we will always rise 0, and run __ from any two points--0 divided by any number is always 0</em>
9. undefined
> because the x variable is always the same, no matter what y variable we graph, we will have the same outcome. So, this would look like a straight line, which have an undefined slope.
> <em>If you think of a slope as rise / run; if you go from any two points, there will be a 0 in the denominator--which is undefined</em>

hope this helps!! have a lovely day :)
The correct answer is A, if you use photomath you can usually find the answers to most algebra problems
If Alexa's mom paid 1/2 of the $450:
$65
if Alexa's mom paid 1/2 of the remaining price:
$145
Alexa's mom paying 1/2 the $450:
$450 divided by 2 = $225
$225 - $120 = $105
$105 - $40 = $65
Alexa has $65 left to pay
Alexa's mom paying 1/2 of the remaining price after the student discount and Alexa payed $120:
$450 - $120 = $330
$330 - $40 = $290
$290 divided by 2 = $145
