Avirus is spreading by a factor of 2 every hour from 1: 00 p. m. to 11: 00 p. m. the function below shows the number of viral infections, f(x), after x hours from 1: 00 p. m.: f(x) = 20(2)x which of the following is a reasonable domain for the function?

entering that problem on the tube might get you an answer

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
