Choose the function whose graph is given by: O A. y = tan(2(x + 7)) - 1
O B. y =tan(x - 2) + 1
O C. y=tan(x + 1) - 76
O D. y = tan(x - ) - 1

Me because some of question i don’t understand

If f(x) = 4 - x2 and g(x) = 6x, which expression is equivalent to (g-f)(3)? 06-3-(4 + 3)2 06-3-(4-33 6(3) - 4 +32 6(3) -4 -32
