Answer:
Step-by-step explanation:
f(x) = 2x - 3
f(-2) = 2(-2) -3 = -4 - 3 = -7
f(-1) = 2(-1) -3 = -2 - 3 = - 5
f(0) = 2(0) -3 = 0 - 3 = -3
f(1) = 2(1) -3 = 2 - 3 = -1
f(2) = 2(2) -3 = 4 - 3 = 1
f(3) = 2(3) -3 = 6 - 3 = 3
The inverse is:
Further explanation:
Given function
<u>Step 1: Replacing f(x) with y</u>
<u>Step 2: Replacing x with y and y with x</u>
<u>Step 3: Solving the equation for y</u>
<u>Step 4: Replacing y with f-1(x)</u>
So, the inverse is:

How to Find the Mean
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
The mean is the same as the average value in a data set.
No it’s 19 because if u have 9 fingers and then add 10 more fingers with it u get 19
Gradient
= (y2-y1)/(x2-x1)
= (-9-(-5))(-2-(-4))
= (-4)(2)
= -8
