Answer : Exponential
The graph is attached below with dots
When we connect all the dots then we will get a curve shaped graph.
a). quadratic
- A U shaped figure is quadratic. It is in the form of parabola.
b). linear
- Line graph is linear. It is a straight line.
c). exponential
- A curve shaped graph is exponential. Like half of a parabola.
d). line - Straight line graph.
By connecting all the dots we got a curve shaped graph. so its exponential.
