59,317 I dno how to explain it but it may be wrong you should do the math yourself to check..
In this case you can say in one hour Austin earns $7.50.
Your answer would be 3 and 1/8
The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.
