Question 51800: Hi. I have no clue on where to start solving the following problem. I tried looking in my textbook, but that didn't help because the examples are so poorly written. The problem asked me to evaluate:
f(x) = 0, for f(x) = square root of (4x^2 - x).
Thank you so much for your help and time.

f%28x%29+=+sqrt%284x%5E2+-+x%29
0+=+sqrt%284x%5E2+-+x%29
0+=+4x%5E2+-+x
0+=+x%284x+-+1%29
x = 0 and 4x - 1 = 0
4x = 1
x = 1/4 and x = 0
