In order to reflect an exponential function across the
y-axis, you.
change the sign of the exponent "X"
change the sign of the initial value "a"
take the reciprocal of the initial value "a"
None of these are correct

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
