Answer:
Step-by-step explanation:
The range is set of all y-values. The range starts from minimum value to maximum value.
We don't have minimum value (approaching negative infinity.)
We have maximum value at x ≈ 2 equal 6.
Therefore the answer is
-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —
Use the slope formula
y2-y1
m=---------
x2-x1
(rise-->y over run-->x)
so it would be
9-5
m=-------
1-10
and that would simplify to
4
----
-9
and that would be your slope.
Hope that helped :-)
Answer:
- 13x² - 19x + 23
- -16x +17
Step-by-step explanation:
1 . (4x² - 9x + 16) + (7 + 9x² - 10x)
4x² - 9x + 16 + 7 + 9x² - 10x
13x² - 19x + 23
2 . (-2x + 6) - (14x - 11)
-2x + 6 - 14x + 11
-16x +17
