For example, if we have two functions f(x) and g(x) that are written as f(x) = x^4/8 g(x) = (8+x)/5 then when x=2, f(x) = (2^4)/8 = 16/8 = 2 = f(2), and g(x) = (8+2)/5 = 2 = g(2). Since both functions equal the same number when their inputs equal 2 (x=2), then the values of both functions are equal when their inputs equal 2. This can be written ...

2020年4月30日 · Therefore, (g o f)(2) = 15. As a side note, there is a second way to solve these kind of problems. Take the entire function f , and plug it into the function g, then plug the number 2 in. Using the example from before: g(x) = 2x + 1. f(x) = 4x - 1 (g o f)(x) = 2(4x-1) + 1 which simplifies to (g o f)(x) = 8x - 1. Now plug in the 2: (g o f)(2 ...

2022年11月8日 · Start on the inside of f(g(2)) and determine what g(2) is. To know that, take the function g(x) = -2x 2 + 4 and plug in x = 2: g(2) = -2(2) 2 + 4 = -2(4) + 4 = -8 + 4 = -4. Then take the -4 you got and plug it into f(x): f(-4) = 3(-4) + 2 = -12 + 2 = -10. So f(g(2)) = -10

f(2) = 2^2 = 4. when you say f(g(x)), then the independent variable in the equation becomes g(x). g(x), however, was the dependent variable in another equation, so it's value had to be calculated before you could put it into f(g(x)). that's exactly what we did above. we solved for g(2) to get 7. then we solved for f(g(x)) to get f(7) = 3.

SOLUTION: Given f(x) = 2x2 + 1 and g(x) = 8x − 9, find the following. ... ...

You can put this solution on YOUR website! Given f(x) = 2x^2 + 1 and g(x) = 8x − 9, find the following:: (a) f(g(2)) = f(8*2-9) = f(7) = 2*7^2+1 = 2*49+1 = 99
