Answer:
16
Step-by-step explanation:
40 can be multiplied by 5, 8 times. 8 multiplied by 2 is 16.
The answer is A, because the Y-intersect starts at -2
Answer:1 7/8
Step-by-step explanation: 5 multiplied by 3 is 15 and 15/8 and since 8 goes into 15 once with 7 left over, the answer is 1 and 7/8
Answer:

Step-by-step explanation:
If a horizontal line intersects the graph of a function in all places at exactly one point (the horizontal line test), the inverse of the function is also a function.
For example, the inverse of a hyperbola (like ƒ(x) =1/x) is a function, because every horizontal line intersects with the graph at exactly one point.
However, the inverse of a parabola (like ƒ(x) = x²) is not a function, because a horizontal line intersects with the graph at two points.
