If you have not yet met integration, here are two ways to approach the problem:

Integration can be considered as anti-differentiation, so see if you can match each function with a function showing its gradient.

Alternatively, integration shows the area under a curve, so by estimating the areas in each interval, you can deduce the shape of the integral function.

Generalise the sum of a GP by using derivatives to make the coefficients into powers of the natural numbers.
