For each function, what is the output of the given input?
For f(x) = 4x + 7, find f(4)
To find f(4), we need to substitute 4 for x in the function f(x) = 4x + 7.
So, plugging in 4 for x, we get:
f(4) = 4(4) + 7
Now let's simplify the expression:
f(4) = 16 + 7
Adding the numbers, we get:
f(4) = 23
Therefore, the output of the given input f(4) is 23.
To find f(4) for the function f(x) = 4x + 7, we need to substitute x with 4 in the function.
Step 1: Start with the function f(x) = 4x + 7.
Step 2: Substitute x with 4 in the function: f(4) = 4(4) + 7.
Step 3: Simplify the expression: f(4) = 16 + 7.
Step 4: Perform the addition: f(4) = 23.
Therefore, the output of the given input f(4) for the function f(x) = 4x + 7 is 23.
