Hello, I need help with this please, thanks.

Which of the following is the average rate of change over the interval [-2, 5] for the function g(x) = log2(x + 3) - 4? (1 point) O O O OA popular video game retailer develops apps. The total profit, in dollars per day, after x days can be modeled by the function R(x) = 2x3 - 20x2 + 26x + 48. The total cost, in dollars per day, after x days, can be modeled by the function A(x) = x2 - 2x - 3. After how many days does the retailer start making money? (1 point) 16 32 64\fGiven f(x) = x2 - 6x + 8 and g(x) = x2 - x - 12, find the y-intercept of 2 (x). (1 point) O WIN O NIC O NI -X +3 Given f (X ) = - X2 + 2x - 3 and g(x) = log4x, evaluate (g - f)(2). (1 point) O NI - Oo O N/ - O 1If f (x) = 2x2 + 4x - 3, then (x+h)-f(x) is equal to which of the following? (1 point) h (2x+2h)2 +(4x+4h)-3-(2x2+4x-3) h 2(x+h)2 +4x-3-2x2 -4x+3 h 2(x2 + 2xh+h2)+4(x+h)-3-(2x2+4x-3) h 2(x +h)2 +4(x +h)-3-2x2 +4x-3Given the values of the linear functions f(x) and g(x) in the tables, where is (f - g)(x) positive?
