I'm assuming the second equation is y=x^2-3 making it a parabola. If you graph both of the equations they intercept at both (-1,-2) and (3,6). So the y coordinates of those would be -2, and 6. I hope that's the answer you're looking for.
D = t * s
you need another variable either t or d

Answer:
If is the amount of salt in the tank at time , then the rate at which the amount of salt in the tank changes is given by
Let's drop the units for now. We have
We're given that the water is pure at the start, so , giving
So the amount of salt in the tank (in lbs) at time is
Step-by-step explanation:
Function is p(x)=(x-4)^5(x^2-16)(x^2-5x+4)(x^3-64)
first factor into (x-r1)(x-r2)... form
p(x)=(x-4)^5(x-4)(x+4)(x-4)(x-1)(x-4)(x^2+4x+16)
group the like ones
p(x)=(x-4)^8(x+4)^1(x-1)^1(x^2+4x+16)
multiplicity is how many times the root repeats in the function
for a root r₁, the root r₁ multiplicity 1 would be (x-r₁)^1, multility 2 would be (x-r₁)^2
so
p(x)=(x-4)^8(x+4)^1(x-1)^1(x^2+4x+16)
(x-4)^8 is the root 4, it has multiplicity 8
(x-(-4))^1 is the root -4 and has multiplicity 1
(x-1)^1 is the root 1 and has multiplity 1
(x^2+4x+16) is not on the real plane, but the roots are -2+2i√3 and -2-2i√3, each multiplicity 1 (but don't count them because they aren't real
baseically
(x-4)^8 is the root 4, it has multiplicity 8
(x-(-4))^1 is the root -4 and has multiplicity 1
(x-1)^1 is the root 1 and has multiplity 1
