Question

Graph the set of points. Which model is most appropriate for the set? ( -1, 20), (0, 10), (1, 5), (2, 2.5) A. quadratic B. linear C. quadratic D. exponential Reset Selection

Answer 1

D exponential because it curves downwards when graphed

Answer 2

Answer:

D. Exponential

Step-by-step explanation:

When we graph the points and join them by lines, we get a curve that is concave up with no maximum or minimum.

Also note that for the points (x,y) in the curve, it holds that $y \longrightarrow 0 \quad \text{as} \quad x \longrightarrow \infty$ and $y>0$ which tells us that model cannot be linear or quadratic.
