? what do you mean. do you have questions that need to be solved?
It's choice C as the root overhead bar goes over all of (x-7) and not just the x. So you have the correct answer.
f(x) = x^4+7
y = x^4+7
x = y^4+7
y^4 = x-7
y = FourthRoot(x-7)
One must use the division property
Same answer as the same question posted earlier:
I believe there should be two different boxes.
From equation 2, it is obvious that the (right) box equals 0.
<span>Putting 0 in the right box of equations 1 & 3, the first (left) box has to equal 1.</span>
