If f (x) = 2x + 3 and G (x + 2) = f (x), then G (x) equals () A. 2x+1B. 2x-1C. 2x-3D. 2x+7

If f (x) = 2x + 3 and G (x + 2) = f (x), then G (x) equals () A. 2x+1B. 2x-1C. 2x-3D. 2x+7


∵ f (x) = 2x + 3, G (x + 2) = f (x), ∵ g (x + 2) = 2x + 3 = 2 (x + 2) - 1, ∵ g (x) = 2x + 3 = 2x-1, so B is selected



It is known that f (x) = 3 - | 2 |, G (x) = x ^ 2-2x, f (x) = g (x). If f (x) is greater than or equal to G (x), f (x) = f (x), if f (x) is less than g (x), then the maximum value of F (x) is a. the maximum value is 3, the minimum value IS-1 b.7-2 root sign 7, no minimum value C. The maximum value is 3, no minimum value d. There is neither maximum nor minimum value
Wrong number. F (x) is 3-2|x|


First of all, do you make sure that there is no wrong data in your title? This title is easy to draw. First draw the image of G (x), and then draw f (x). F (x) is a straight line parallel to the X axis, and then according to the conditions you give, you can easily draw the image of F (x). It should be a straight line parallel to the X axis with a small bend, and that
