If f(x) = x2 − 1, and f(2a) = 35, then what could be the value of a ?

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.

Which equation represents the function on the graph?

Is there an x intercept in the equation 60*1.15^x
