Answer:
Step-by-step explanation:
step 1
Find the equation of the solid line
Find the slope
we have
(0,0.2) and (3,2.2)
The y intercept b is equal to
so
the equation of the solid line in slope intercept form is equal to
step 2
Find the equation of the inequality
we know that
The solution of the inequality is the shaded area below the solid line
therefore
Answer:
it is congruent
Step-by-step explanation:
The color magenta! Or purple
The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
A graphing calculator working the quadratic regression problem for these three points gives the equation as
y = 2x² +7x -5
