Question 250264: Evaluate the logarithmic equation for three values of x that are greater than 1, three values of x that are between 0 and 1, and at x=1. Use the resulting ordered pairs to plot the graph. State the equation of the line asymptotic to the graph (if any).
y = log1/7 (x+2)
THIS IS MY ANSWER NOT SURE IF IT RIGHT, I ALSO NEED TO GRAPH IT I DO NOT KNOW HOW TO DO THAT CAN YOU SHOW ME. PLEASE!!!!!!!!!!!!!!
x=1 ; y =-0.5646
x = 1/3; y= -0.4354
x = 1/2; y = -0.4709
x = 3/4; y = -0.5199
x = 2; y = -0.7124
x = 3; y = -0.8271
x = 4; y = -0.9208
Thank you, so much.

You can put this solution on YOUR website!
y = log1/7 (x+2)
y+=+log%28%281%2F7%29%2C%28x%2B2%29%29
Change it to common logs, so you can use a calculator more easily.
y+=+log%28x%2B2%29%2Flog%281%2F7%29
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.

The easy way:
dl the FREE software from

and it will find the points and make the graph.
