Answer:
y=7.5x, y=60
Step-by-step explanation:
you have to consider x as the input and y as output
when input x=2 the output y=15 so it grew by 7.5 so we can say that y= 2*7.5
in general the equation is y= 7.5*x
when x=8 we will have y=7.5*8=60

Answer:
x in {-6, -2, 4}
Step-by-step explanation:
The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.
x +6 = 0 ⇒ x = -6
x -4 = 0 ⇒ x = 4
x +2 = 0 ⇒ x = -2
The zeros of the function are the x-values -6, -2, and 4.
