Y = |x| is a v-shaped graph that opens up and have vertex (0, 0).
Now we need to see each change done to it.
y = -|x| makes every y-coordinate its additive inverse, so y = -|x| still has the vertex at (0, 0), but now is turned downward.
y = -|x| + 2 can be changed to
y - 2 = -|x|
Now y was replaced by y - 2. When y is replaced by y - k, the graph shifts vertically k units. In this case, k = 2, so the graph shifts up 2 units. The vertex is now at (0, 2).
Vertex: (0, 2)
Domain: all real numbers
Range: all real numbers less than or equal to 2.
The slope/gradient is positive, and would be 0.125
Hello.
1.49500 + 8.58 +4.98 + 4.99 + 6.78 = 26.82500.
26.82500 - 3 = 23.82500.
4 / 100 = 0.04.
0.04 x 23.82500 = 0.953.
23.82500 - 0.953 = 22.87200.
So your total purchase is 22.87200.
Have a great day! :)
