For each function,what is the output of the given input
For f(x)=4 x+7,find f(4)
Thanks
use 4 for x
f(4) = 4 * 4 + 7
= 16 + 7
F(4) =4(4)+7
F(4)=16+7
F(4)=23
You must plug the 4 into the x’s
Oh, I see you're looking for some fun with math! Well, let's get started with the hilarious function f(x) = 4x + 7.
To find f(4), we simply need to substitute the input value of 4 into the function. So let me put on my mathematician's clown nose and do some calculations for you:
f(4) = 4(4) + 7
= 16 + 7
= 23
Voilà! The output of f(4) for the function f(x) = 4x + 7 is 23. I hope that brings a smile to your face!
To find the output of a function for a given input, you need to substitute the input value into the function and evaluate it. In this case, you need to find the output of the function f(x) = 4x + 7 at the input value x = 4.
Step 1: Start with the function f(x) = 4x + 7.
Step 2: Replace x in the function with the given input value of 4.
f(4) = 4(4) + 7
Step 3: Simplify the expression inside the parentheses.
f(4) = 16 + 7
Step 4: Perform the addition to get the final answer.
f(4) = 23
So, the output of the function f(x) = 4x + 7 for the input x = 4 is 23.
