Please show all clear steps, thank you.For each of the following function, find:a) (f+g)(2) b) (f-g)(-3) c) (f/g)(-4)1) f(x) = -2x+3 and g(x) =... 顯示更多 Please show all clear steps, thank you. For each of the following function, find: a) (f+g)(2) b) (f-g)(-3) c) (f/g)(-4) 1) f(x) = -2x+3 and g(x) = -1/2 ———————————————————————————————————— For each of the following function find: a) (f+g)(x) b) (f-g)(x) c) (fg)(x) d) (f/g)(x) Write each function in simplest form and write down the restrictions, if any. 2) f(x) = 3 root x then +1 and g(x) = -2 root x 請各位大大幫幫助，仲有想問下呢d數學題係屬於中學幾年級？謝謝！^^

你可以當大概中四程度。 我暫時無時間, 只做第一題: a) (f+g)(2) = f(2) + g(2) = -2(2) + 3 + (-1/2) = -3/2 b) (f-g)(-3) = f(-3) - g(-3) = -2(-3) + 3 - (-1/2) = 19/2 c) (f/g)(-4) = f(-4)/g(-4) = [-2(-4) + 3]/(-1/2) = -22 2014-09-13 01:50:53 補充： (????)你可以當大概中四程度。 圖片參考：https://s.yimg.com/rk/HA00430218/o/1204946964.png其他解答:
