Is the work shown below correct? Explain your answer. (11 + 21 ) - ( 3 = 100)
= 11 + 21 - 3 - 101
= (11 - 3) + (21 - 101)
= 8 - 81

What is the inverse of the function f(x) = 2x + 1?

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.
