Is the sequence 7, 28, 112, 448, . . arithmetic or geometric?

Geometric

Step-by-step explanation:

You can identify a sequence based off of how the next term appears

if it is subtracting/adding you will get a common difference

if it is dividing/multiplying you will get a common ratio

When you look at the change between 7 and 28 it is multiplied by 4

this can be applied onward:

28 x 4 = 112

112 x 4 = 448 etc;

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
