If f (4) is the input then you need to insert the 4 for X.
so f(4)= 4×4+7
f (x)= 23

Answer:

Step-by-step explanation:

f(x) = 4x+7

Here f(x) is the function defined for x .

so when we need f(4) we replace the x in the equation by 4 to get f(4)

f(x) = 4x+7

f(4)=4.4+7

Now we need to simplify it to get the required value

f(4) =16+7

f(4)= 23
