Webf (g (x)) = 2 (4/x) + 1 = 8/x + 1 This is just a simple example but you can do it with many more complicated formulas as well. For example: (given f (x) = 2x+3 and g (x) = -x^2 + 5 ( f o g) (x) = f (g (x)) = f (–x^2 + 5) = 2 (g (x)) + 3 = 2 (–x^2 + … WebMethod 1: Substitute x=2 x=2 into the combined function h h. \begin {aligned}h (x)&=3x+1\\\\ h (2)&=3 (2)+1\\\\ &=\greenD {7} \end {aligned} h(x)h(2)=3x+1=3(2)+1=7 Method 2: Find f (2) f (2) and g (2) g(2) and add the results. Since h (x)=f (x)+g (x) h(x)=f (x)+g(x), we can also find h (2) h(2) by finding f (2) +g (2) f (2)+g(2).

WebJan 26, 2024 · For two given functions f (x) and g (x), the function (f + g) (x) is: (f + g) (x) = f (x) + g (x) Here we have the functions: f (x) = x^2 + 1 g (x) = 5 - x Now we want to find (f + g) (x), we can use the above expression: (f + g) (x) = f (x) + g (x) = (x^2 + 1) + (5 - x) (f + g) (x) = x^2 +1 + 5 - x = x^2 - x + 6 (f + g) (x) = x^2 - x + 6 WebOct 19, 2024 · Your math textbook may use a function notation like this: f ( x )=2 x +1. To graph a function in your calculator, you must realize f (x) is interchangeable with y, only the notation differs. See the third screen. When you’re defining functions, the only symbol the calculator allows for the independent variable is the letter X. Press dan west northern ireland
