Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D

The statement that is true about the dot plots is: Range for Week 1 equals range for Week 2.
<h3>What is the Range of a Data Set?</h3>
Range is simply the difference between the highest data point and the lowest data point in a data set.
Range for Week 1:
Range = 89 - 62
= 27
Range for Week 2:
Range = 89 - 62
= 27
The sentence of median and mean doesn't satisfy the situation.
Hence, Range for Week 1 equals range for Week 2.
