If a vertical line crosses the relation on the graph only once in all locations, the relation is <span>a </span>function. If<span> a vertical line crosses the relation more than once, the relation is </span>not a function<span>. So number 18 is not a function but number 19 is a function.
Hope this helps!!</span>

Shop B. This is cause shop A charges about $1.25 for each g of peanut butter, while Shop B charges only $1.20 for each g of peanut butter. Hope this helps!
Answer: Choice C)
Stretched vertically, flipped over x axis, shifted 7 units down
------------------------------------------------
Explanation:
Going from y = x^3 to y = 2x^3 means the graph is pulled vertically so that each (x,y) point has the y coordinate that is doubled. Example: (1,1) turns into (1,2). If this applies to all the points, then the graph is stretched vertically by a factor of 2
Going from y = 2x^3 to y = -2x^3 flips the graph over the y axis. For example, the point (1,2) flips to (1,-2). The x coordinate stays the same with the y coordinate flipping in sign.
The last transformation is the shifting 7 units down which is taken care of by the "-7" tacked at the end. Essentially we subtract 7 from each y coordinate. Example: (1,-2) becomes (1,-9)
Answer:
x=11 and the number of solutions is one solution
Step-by-step explanation:
The square root of 121 is 11. There are no other solutions, I believe.
