Answer:
A. 660 miles
Step-by-step explanation:
420 ÷ 7 = 60 60 x 4 = 240 240 + 420 = 660
4/100= x/4,500
18,000/100= $180x2.5 = $450
The output of the function when x=4 is 23
<h3>How to determine the output</h3>
Given the function as;
f(x)=4x+7
We are told to find f ( 4)
This explains that we should substitute the value of x as 4 in the function:
To find the value of the function at x = 4 we have:
If f(x)=4x+7
Then,
Put 4 as a replacement for x, we have:
f ( 4) = 4 ( 4) + 7
Expand the bracket
f ( 4) = 16 + 7
Add the values
f ( 4) = 23
The value of the function is 23
We can see that the value of the function when x is 4 is 23
Thus, the output of the function when x=4 is 23
The complete question is;
For each function what is the output for the given input?
For f(x)=4x+7, find f(4)
