The rectangle has an area of 4(x+3) square units.
a- if the dimensions of the rectangle are doubled, what is the area of the new rectangle in terms of x? show your work.
b- will the ratio of the area of the original rectangle to the area of the larger rectangle be the same for any positive value of x? explain.

answer: 25 is the correct answer

step-by-step explanation:

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.
