For f x 2x+1 and g x x 2-7 find f-g x
WebJun 4, 2024 · Answer: (f + g) (x) = 7x - 1 Step-by-step explanation: Given : f (x) = 5x – 2 and g (x) = 2x + 1 We have to find (f + g) (x) Consider (f + g) (x) = f (x) + g (x) Also, given f (x) = 5x – 2 and g (x) = 2x + 1 Substitute, we have, f (x) + g (x) = 5x - 2 + 2x + 1 Like Terms are terms having same variable with same degree. WebIt is f ( x) − 1 right. So let us find f ( x) inverse. f ( x) = x 2 + 1 then f ( x) − 1 = x − 1 right [ just swipe the x with f ( x) and solve for f ( x) that should give you this result] now go to the first function g ( f ( x)) [this function is the same as g ( x 2 + 1) right.]

Did you know?
f (x) = 2x + 1. g (x) = x^2 - 7. We will plug our equations for f (x) and g (x) into f (x) + g (x) as shown: (f+g) (x) = 2x + 1 + x^2 - 7. Now we will combine like terms (which is only the -7 and 1) (f+g) (x) = 2x + x^2 -6. Let's put it in order and get our answer! (f+g) (x) = x^2 + 2x -6. Upvote • 0 Downvote.
