How do I find (fog) (x) with the given equations f (x)=8x+2
Jul 8, 2014 · 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
how to find (fog) (x) if it is in fraction | Wyzant Ask An Expert
Jan 2, 2017 · 1 Expert Answer. f [g (x)]=0 is to be demonstrated. NOTE: You were careless in preceding this with both : and -, neither of which is helpful. f is assumed to be the rational function having 3x+4 as numerator and 3x - 4 as denominator, BOTH OF WHICH SHOULD HAVE BEEN PARENTHESIZED. A similar remark applies to g. But in this case, the claim is not ...

1 and g (x) = x - 5. calculate (fog) (1) and (gof) (1) - Wyzant
Feb 16, 2021 · 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!

If f (x)=x^2+5 and g (x)=5x+4 what is [fog] (6) - Wyzant
Mar 20, 2019 · The variable in the expression for f (x) should be replaced with g (x), as follows: ( )^2 +5. This expression is (5x + 4)^2 + 5, which is 25x^2 + 40x + 16 + 5. Notice that the constant of 5 is STILL in the expression. Now simplify, by combining LIKE TERMS, to 25x^2 + 40x + 21. Therefore, f o g ( x) = 25x^2 40x + 21. That's it! Upvote • 0 ...

If f(x)=2x and g(x)=x+5, find (fog)(x) | Wyzant Ask An Expert
Nov 4, 2014 · The short way to write that is f (4). So, if f (x) = 2x + 5, and we want to know f (4), we put 4 in for x. f (4) = 2 (4) + 5 = 13. f (6) = 2 (6) + 5 = 17. Instead, we have f (x) = 2x and g (x) = x + 5. Another way to write fog (x) is f (g (x)). This means that for each x in f (x), we are going to plug in g (x). f (g (x)) = 2 (x + 5) = 2x + 10.
