Question 250264
y = log1/7 (x+2)
{{{y = log((1/7),(x+2))}}}
Change it to common logs, so you can use a calculator more easily.
{{{y = log(x+2)/log(1/7)}}}
Then you can use a calculator, or Excel to find the values for y.  The 1st value you have is correct, but I didn't check the others.
-------------------
To graph it, plot all the points you've calculated and draw a smooth curve thru them.
If any of the values of y are not correct, it will be obvious when you plot them.
