An x intercept is always where y = 0. If y = 2 log(10x), then let y = 0, and solve for x.
2 log(10x) = 0
log(10x) = 0
log%2810%2C10x%29+=+0
10%5E0+=+10x
1+=+10x
x=+1%2F10

A y intercept is always where x = 0. If y = 2 log(10x), then y = 2 log(0), which is undefined.

Conclusion: X-intercept (1%2F10,0). There is NO y-intercept.
