The function ff is defined for all real numbers. The graph

y=−2f(3−x)+5y=-2f(3-x)+5

has a unique minimum at (1,−7)(1,-7).

At which point does the graph

y=f(2x+1)+4y=f(2x+1)+4

have its maximum?

A(−12,10)\left(-\dfrac12,10\right)
B(12,2)\left(\dfrac12,2\right)
C(12,10)\left(\dfrac12,10\right)
D(1,10)(1,10)
E(2,10)(2,10)
F(5,10)(5,10)
