Work Step by Step

Note that for any real number value of $x$, the value of $a^x$ will never be zero. Thus, the graph of an exponential function of the form $f(x) = a^x$ will never have a y-value of 0. This means that its graph will not touch the x-axis and hence, has no x-intercept. Therefore, the given statement is true.
