Answer:
- domain: [0, 7]
- range: [-2, 4]
- is a function? YES
Step-by-step explanation:
The domain is the horizontal extent, which is from x=0 to x=7.
The range is the vertical extent, which is from y=-2 to y=4.
The curve passes the vertical line test, so the relation IS A FUNCTION.
_____
The vertical line test asks whether any vertical line intersects the curve at more than one point. If so, the relation is NOT a function.
Step-by-step explanation:
-12x < -12
-12x/-12= x
-12/-12= 1
x < 1
8x7x6 = 336. There are 8 possible options for slot 1, then 7 for 2, and 6 for the last slot.
(x-7)(x+12)
X^2 +12x-7x-84
x^2+5x-84. <- answer
