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)

Answer:
y= -2x-1
Step-by-step explanation:
slope intercept form is y= mx+b
m is the slope or rate
and b is the y intercept and it is where x is zero
to find the slope is rise of run or y/x so your answer is

Answer:
82.8 m^2
Step-by-step explanation:
Find area of front-facing triangle: 1/2(6)(8.8)=26.4
26.4*2=52.8
Find area of side-facing triangle: 1/2(2)(9)=9
9*2=18
Find area of rectangular base: 6(2)=12
Add it all up: 52.8+18+12=82.8
Therefore, 82.8 m^2
