Answer:
Step-by-step explanation:
You shift up and down when there is a value at the end of the function outside of the parentheses. Since it is -1, you shift down one.
You shift left and right when there is a value inside the parentheses. Since it is 2, you shift left 2. Remember that you always shift left if the number positive and you shift right when it is negative.

Answer: f⁻¹(x)=(x-7)²
Step-by-step explanation:
To find the inverse function, we want to switch the y with the x and vice versa. Then we solve for y.
[switch y with x and x with y]
[subtract both sides by 7]
[square both sides]
Now, we know that f⁻¹(x)=(x-7)².
Answer:
-6v < -3; v> -0.5
Step-by-step explanation:
We have to find a number let say x
Given that:
-6v < x ........... eq1
v> - 0.5 ........... eq2
By taking equation 1
-6v < x
Dividing both sides by -6
(inequality will be inverted because of negative sign)
-6/-6 v > x/-6
v > x/-6 .........eq3
Now comparing eq2 and eq3 we get:
x/-6 = -0.5
Multiplying both sides by -6
x = -0.5 * -6
x = -3
So it will give:
-6v < -3; v> -0.5
I hope it will help you!
