Match the y-coordinate with the given x-coordinate for the equation y = log2x.

1. 8
1
2. 4
3
3. 2

If we evaluate the function at the given points, we have:

In fact, the function returns, for a given number , the exponent you have to give to 2 to obtain .

So, you want to obtain 8, you have to raise 2 to the 3rd power, if you want 4 you have to raise 2 to the 2nd power, and so on.

the answer would be c:   ax + b = ax + c
