2014年7月8日 · How do I find (fog)(x) with the given equations f(x)=8x+2 and g(x)=x^2-8 ? normally I would know hoe to solve this is a number was in the place of the x but since the x is there, I'm stuck. Follow • 2

2021年2月16日 · First, what fog(1) means is: g is a function of f, evaluated at 1. Another notation for fog(1) is: f(g(1)) What it means is that wherever there is an x in the f(x) function, replace that x with the entire function g(x). Simplify, then evaluate the result using x=1. How do you do it? Thankfully, its simpler than its explanation!

2014年11月4日 · We cannot find a value for x with just this. Instead, we would say what is the value of 2x + 5 if x = 4 (or some other number). The short way to write that is f(4).

But in this case, the claim is not true. When you substitute the g function's rational expression for x everywhere that x appears in the expression for f, you will be required to get a common denominator in two places, i.e. a four storey division problem will arise.
