Answer:
Domain: {-2, -1, 0, 1, 2}
Range: {-5, -1, 3, 7, 11}
Step-by-step explanation:
Given the function, f(x) = -4x + 3:
We could simply substitute the given x-values into the function to solve for its corresponding y-values:
x = -2:
f(-2) = -4(-2) + 3
f(-2) = 8 + 3
f(-2) = 11
x = -1:
f(-1) = -4(-1) + 3
f(-1) = 4 + 3
f(-1) = 7
x = 0:
f(0) = -4(0) + 3
f(0) = 0 + 3
f(0) = 3
x = 1:
f( 1 ) = -4( 1 ) + 3
f( 1 ) = -4 + 3
f( 1 ) = -1
x = 2:
f(2) = -4(2) + 3
f(2) = -8 + 3
f(2) = -5

Answer:
1.39y
39% is .39. It's an additional 39%, so you add .39 to (1)y. That would give you 1.39 y. Hop this helps! :D
The florists charges and delivery are illustrations of linear functions
The amount made by the florist per delivery is y = 1.5 + 0.25x
<h3>How to determine the functions</h3>
For the charges, we have:
- Delivery = $5.00
- Rate = $1.00 per mile
Represent the cost with y, and the number of miles with x.
The function that represents the amount the florist made is:
y = 5 + x
For the delivery, we have:
- Gas = $3.50
- Rate = $0.75 per mile
The function that represents the delivery is:
y = 3.5 + 0.75x
The amount made by the florist per delivery is then calculated as:
y = 5 - 3.5 + x - 0.75x
y = 1.5 + 0.25x
