The inverse of a function f is a function f^(-1) such that, for all x in the domain of f, f^(-1)(f(x)) = x. Similarly, for all y in the domain of f^(-1), f(f^(-1)(y)) = y

【方法一】 f(x+1)=x+6=x+1+5 。 将上述表达式里的 (x+1) 替换为 x ，则有. f(x)=x+5 。 【方法二】注意到 f(x)=f(x-1+1) ， 将已知函数表达式里面的 x 替换为 (x-1) ，可得. f(x-1+1)=(x …

2018年11月20日 · To graph the function f (x) = − 1.5 x + 6, we can identify two key components: the slope and the y-intercept. Identify the y-intercept (b): In the equation f (x) = − 1.5 x + 6, the …
