2 points. You answer this with the vertical line test. There are two pairs of points with the same x-axis, so they make two vertical lines. For it to be a function, it must pass the vertical line test, so no two points have the same x-axis. I hope this helps :)
That would be..........
C) 62
62 x 1.25 = 77.50
109.75 - 77.50 = 32.25
32.25 / .75 = 43
So, 62 large at 1.25 ea.
and 43 small at .75 ea.
Answer:
= 177.66
Step-by-step explanation:
you add all the pounds gained by group A in the 3 weeks which is 59.22 and then you multiply by 3 to give you 177.66

f(x) has to be close to -1 when x is close to -3, and so f(x) is increasing when x increases, and there are no numbers from -1 to ∞ that there is no f(x) value. In the first piece of the function <span>f(x) ranges from -1 to 4 and the second piece from 0 to ∞ so. The ranges had to overlap since it's not defined at x = 2.</span>
