i need help asap.

1. Graph the function y = 2x . 2. Graph the function y = 4*+2, using a shift of the standard function, y = 4*. Shift: TTTT 3. A radioactive substance decays in such a way that the amount of mass remaining after t days is given by m(t) = 12e-0.011t where m(t) is measured in kilograms. How much of the mass remains after 25 days?1. Graph the function y = 2x . 2. Graph the function y = 4*+2, using a shift of the standard function, y = 4*. Shift: TTTT 3.
