I suppose that function is [tex] y=7\cdot 6^{x+2}+1 [/tex].
The function [tex] y=6^x [/tex] is increasing and takes positive values for all x. Then the function [tex] y=7\cdot 6^{x+2}+1 [/tex] is also increasing and takes positive values for all x. So, option B is incorrect, because this function is decreasing and options C and are incorrect, because there y can be negative.
Answer: correct choice is A.
