Question

When graphing y = x2 – 14x + 24 and y = 20 – |x + 3|, which value would be the best minimum x- and minimum y-values for the viewing window so that all intercepts, minimums, maximums, and points of intersection are able to be seen as closely as possible?

–50
–45
–25
–20

Answer 1

Answer: -45

It would be better if 30 were an option!

Explanation:

At 25, all the important points will be in the graph-- barely. The vertex of the first equation is right at -25! So to be safe, it is better to go a bit larger.

If the viewing window is much larger, it is difficult to see small increments on the scale.

Answer 2

-25
