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 $\frac{1}{8}x^2+15$

Answer:

1.) Tan C = $\frac{12}{5}$

2.) Sin Z = $\frac{24}{26}$ or $\frac{12}{13}$ if reduced

3.) Cos A = $\frac{15}{17}$

4.) Cos A = $\frac{12}{37}$

Step-by-step explanation:

Let's keep in mind that;

Sin = $\frac{opposite}{hypotenuse}$

Cos = $\frac{adjacent}{hypotenuse}$

Tan = $\frac{opposite}{adjacent}$
