The graph of the function \displaystyle f(x) = 4^x-3*1 \displaystyle can be obtained from the graph of g(x)=4x\displaystyle {g{{\left({x}\right)}}}={4}^{{x}} by one of the following actions:
(a) shifting the graph of g(x)\displaystyle {g{{\left({x}\right)}}} to the right 3 units;
(b) shifting the graph of g(x)\displaystyle {g{{\left({x}\right)}}} to the left 3 units;
(c) shifting the graph of g(x)\displaystyle {g{{\left({x}\right)}}} upward 3 units;
(d) shifting the graph of g(x)\displaystyle {g{{\left({x}\right)}}} downward 3 units;
(e) reflecting the graph of g(x)\displaystyle {g{{\left({x}\right)}}} in the x\displaystyle {x}-axis;
(f) reflecting the graph of g(x)\displaystyle {g{{\left({x}\right)}}} in the y\displaystyle {y}-axis;
Your answer is (input a, b, c, d, e, or f)
Is the domain of the function f(x)\displaystyle {f{{\left({x}\right)}}} still (,)\displaystyle {\left(-\infty,\infty\right)}?
Your answer is (input Yes or No)
The range of the function f(x)\displaystyle {f{{\left({x}\right)}}} is (A,)\displaystyle {\left({A},\infty\right)},
the value of A\displaystyle {A} is
