Hi Mr. G. I was just wondering if my answer is correct for 17a because the back of the textbook is confusing me.
Your answer is correct (just change those x's to t's in the domain)! The book's answer comes from expanding (multiplying) the bracket the second piece of your function by the 0.03 and collecting like terms. It's correct, but it's not necessary to expand. You can leave the answer in the form you have it. Have a good day!
