Answer:
(c) output increases, then decreases ...
Step-by-step explanation:
The given function is quadratic, so it has a turning point. Neither linear nor exponential functions have a turning point, so are always increasing or decreasing.*
The second attachment shows a plot of the function with input on the x-axis and output (area of the rectangle) on the y-axis.
_____
* A linear function that is a horizontal line will be neither increasing nor decreasing.
Answer:
The answer is
<h2>y = - 4x + 7</h2>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = - 4x + 2
Comparing with the general equation above
Slope / m = - 4
Since the lines are parallel their slope are also the same
Slope of parallel line = - 4
So the equation of the line using point (0,7) and slope - 4 is
We have the final answer as
<h3>y = - 4x + 7</h3>Hope this helps you
