The question is below

1. The rule is that for something to be a function, one input(x-value) can ONLY HAVE ONE output(y-value). If one input has more than one output, it is not a function. Your answer is #1 because you can only have 1 output

2. Since you've been given the input -> x = -10, substitute/plug it into the equation to find the output:

     Plug in -10 into "x"

y = -15 + 6

y = -9         Your answer is #2

x=half

step-by-step explanation:

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
