Answer:
The inverse function is f(x) = x^2 - 3
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = √(x + 3)
x = √(f(x) + 3)
Now solve for the new f(x). The result will be your inverse function.
x = √(f(x) + 3)
x^2 = f(x) + 3
x^2 - 3 = f(x)
4r²<span>– 16 = 84
4r</span>² = 84+16
4r²= 100
r²=25
r=√25
r=<span>±5</span>
The answer is C and E.
We need to first understnad that percentage can be converted into decimal numbers and fraction:
100% = 1.0 or 100/100
Hence:
40% = 0.4 or 40/100
To find the percentage of number, we use multiplication (which is also represented by the dot in the above options).
As C. and E. has the correct value, they are the correct answers.
Hope it helps!
