Which calculator do I graph the following equation with? I feel like I've tried them all, but I keep getting a syntex error.

y=31n^3sqrt(x-4)

Thanks

You need to enter it differently:

y=3(ln(sqrt(x-4)))^3

In this way, you are taking the natural log of the square root of x-4, cubing it, and then multiplying by 3. I imagine that is what you intended.

So, in any of the function graphing calculators, you just enter the right side, and in any of the equation graphing calculators, you enter the whole equation.

Hope this helps!
