Answer:
1.40f .
Step-by-step explanation:
One answer could be:
In March the house had f + 40% of f
= f + 0.40f
= 1.40f
To find the inverse of this function, we first need to replace f(x) with y.
y = 2x^2 + 3
Now, we swap x and y
x = 2y^2 + 3
Now, we solve for y.
-3
x - 3 = 2y^2
Sqrt both sides.
√(x - 3) = 2y
Divide by 2
√(x - 3)/2 = y
Replace y with f^-1(x)
√(x - 3)/2 = f^-1(x)
Just realized you were asking for f(-1), not f^-1(x)
Feels bad.
f(-1) = 2(-1^2 + 3)
f(-1) = 2(-1^5)
f(-1) = 2(-1)
<u>f(-1) = -2</u>
I'm leaving the original answer in case you also need the inverse function. :)
Answer:
The dependent variable depends on the independent variable.
Step-by-step explanation:
- The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable...
- The values of the independent variable can be changed as per requirement, by the researcher...
- Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment.
- An independent variable is a presumed cause whereas dependent variable is a measured effect.
- In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x
