Hi, I am just wondering if I have the correct understanding of the questions below (in image)
For question 1. I got the highest value of the function is 19. I got this by subbing in 7.5 because the |x - 7| < 0.5 because it is looking 0.5 units within x=7. So the highest value has to be when it is either 6.5 or 7.5. It turns out f(7.5) = 19 was the highest value. Therefore, the answer is 19 correct? I am wondering because it does not include 7.5, therefore the highest value of the function has to be the limit of f(x) as x approaches 7.5, which is 19.
For question two. The 0.3 units of 22. The 22 is the y-value of the function correct?
