X-the number
16 + 2x = -24 |subtract 16 from both sides
2x = -40 |divide both sides by 2
<u>x = -20</u>

Answer:
C. quadratic
Step-by-step explanation:
You can rightly guess that ballistic motion is described by a <em>quadratic</em> function.
Differences of the y-values are 5.75, 3.25, 0.75, -1.75, -4.25.
First differences are not constant, but form a linear sequence that decreases by 2.5 between each pair. Since second differences are constant, the function is described by a 2nd-degree polynomial function, a <em>quadratic</em>.

<em>Comment on other function types</em>
Linear functions have constant first differences. Exponential functions have exponentially increasing first differences. Logarithmic functions have first differences that increase by smaller and smaller amounts.
Use the duplication of computes which can resolve to the coordinates of the slope
