Brittney is a scientist. She is recording the number of cells in a dish. After each hour, the cell divided into four cells. The sequence shown represents the growth of the cells. 1, 4, 16, 64, 256,…
Which explicit formula represents this situation?

A. gn = 4n-1
B. gn = 4 • 1n-1
C. gn = -4n-1
D. gn = -4 • 1n-1

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

hi how are you doing today, if you need just ask me.
