What is the value of c

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.

What are the domain and range of the function f(x)=2^x+1

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)
