Jennifer starts with a population of 100 amoebas that doubles in size every minute for a number of minutes, m. She writes the expression 100(2^m)to find
the number of amoeba after m minutes.
Nathan starts with a population of 10 amoebas that increases 40% in size every
minute for a number of minutes, m. He writes the expression (1+0.4)^m to find
the number of amoeba after m minutes.
Use the drop-down menus to explain what each part of Jennifer's and Nathan's
expressions mean.

no i do not : ( what is it?

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
