For 12 - 14, tell whether the function has a minimum value or a maximum value. Then find the minimum or maximum value. Remember: the y-coordinate (only) of the vertex is the minimum/maximum value of the function. 12) f (x) = -3x2 +18x-5 13) g(x) = 9x2 +7 14) h(x) = --x _X2 -7x + 2 calculator Allowed! 15) A woodland jumping mouse hops along a parabolic path given by y = -0.2x2 +1.3x where x is the mouse's horizontal position (in feet) and y is the corresponding height (in feet). Can the mouse jump
