the number of bacteria in a sample increased by a factor of 1.02 every minute from the time shown in the graph. the function shows the number of bacteria in the sample f(x) after x minutes from 9: 05 a. m:
f(x) = 10(1.02)x
exponential graph showing time in minutes on the x axis and number of bacteria on the y axis going through zero comma ten and approximately fifty comma twenty seven

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
