The result of the given expression f(x) + f(x) + f(x) = 3x².
<h3>What is defined as the quadratic function?</h3>
A quadratic function is one of the following: f(x) = ax² + bx + c, where a, b, and c are positive integers and an is not equal to zero.
- A parabola is a curve that represents the graph of a quadratic function.
- Parabolas can open up or down, and their "width" or "steepness" can vary, but they all share the identical basic "U" shape.
- A quadratic equation is defined in mathematics as an equation of degree 2, which means that the highest exponent of the this function is 2.
As per the given question;
f(x) = x²
Now, we have to estimate the value of the function;
= f(x) + f(x) + f(x)
Substitute the value of f(x).
= x² + x² + x²
= 3x²
Thus, the value of the given function is found as 3x².

To find Matt's typing rate, divide (4/5 page) by (2/5 hour).
Note that since both denominators are 5, we can drop the denominators. Then, Matt's rate is 4 pages divided by 2 hours, or 2 pages/hour. That's his typing rate.
Step-by-step explanation:
I guess we can simply assume that the month has 4 weeks.
1 month = 4 weeks = 4×40 = 160 hours = $1850.00
that means in 1 hour he gets
1850/160 = $11.5625 ≈ $11.56
that is what "hourly rate" means.
Replace the f(x) with y and proceed to make x the subject:
y=1/3x+5
y-5=1/3x
We need to ÷1/3 on both sides, so ×3 on both sides
3(y-5)=x
3y-15=x
Now swap y with x and replace the isolated x with f(x) so the inverse function is:
Your answer would be 2.6 meters per second
390 ÷ 150 = 2.6
