Answer:
f=2
Step-by-step explanation:
First, you move the variables to the left side of the equation and change its sign.
After doing so, you have 4f -5f =2.
Now, combine like terms. 4f-5f = -f, or -1f. Either way is fine.
Your equation looks like this now: -f = -2
Now remove the negative symbols due to their being one on both side.
f=2
Mark brainliest if possible please! Have a nice day.

I’m pretty sure I had the question before
Answer:
1x² + 1x -3
Step-by-step explanation:
A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
To compute manually the values of a, b and c is a rather complicated process using a technique known as least squares method.
However, we can use a scientific calculator to compute the three values and arrive at the quadratic equation
Using the points provided, the values are:
a = 1, b = 1, c = -3
The function is 1x² + 1x -3
Note that this is a best-fit function it does not necessarily pass through all 3 points but approximates. The attached graph shows that the function does indeed pass through 2 of the 3 points
