The temperature of a chemical compound, in degrees Celsius, changes when the compound is exposed to UV light. The table below sh

SIZIF [17.4K]

So, we are given the y intercept, and since we know c is the same as the y value of the y intercept, we know that c=15.

From there we can pick any two of the points given to us to find our a and b.

Let's use (4,17) and (8,23) becase they are whole numbers.

$17=16a+4b+15\\ 23=64a+8b+15 \implies \\ 2=16a+4b\\ 8=64a+8b \implies\\ 8=64+16b \\ 8=64+8b \implies \\ 0=8b \implies\\ b=0$

So, with b=0, we can plug it back into the first equation to get: $17=16a+4b+15 \implies\\ 2=16a \implies\\ a=\frac{1}{8}$

So our quadratic is $\frac{1}{8}x^2+15$

The answer would be x^4 -16
Explanation: use the FOIL method.
(x^2 +4)(x^2 -4)= x^4 +4x -4x -16. 4x and -4x cancel each other out. You are left with x^4 -16.
