[math]f.4數學一問
發問:
Given that f(x) is a function of x and f(a+4)=8a-12,for any real number a.Find f(x).
最佳解答:
Since f( a + 4 ) = 8a - 12 Hence f( a + 4 ) = 8( a + 4 ) - 44 By substituting x = a + 4, we have f( x ) = 8x - 44 =========== This is the typical problem solving method. Hope I have helped you.
