What was the equation of the graph below before it was shifted to the right 1 unit? (equation was g(x)=(x-1.5)^3-(x-1.5))
harina [27]
If graph of the function y=f(x) was shifted to the  right 1 unit, then you got new function y=f(x-1).
Reversly, if you have the function g(x)=(x-1.5)^3-(x-1.5) that is obtained by shifting to the right 1 unit, then the initial function was

g(x+1)=(x+1-1.5)^3-(x+1-1.5), \\ g(x+1)=(x-0.5)^3-(x-0.5).
Answer: Correct choice is D.

I’ll give brainliest to the person who answers this right. Please help!!
Charra [1.4K]

Answer:

3.43

Step-by-step explanation:

To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
