Step-by-step explanation:
How are we supposed to help...?
Let, the length = l
Width = l/2
Area = l * w = l * l/2 = l²/2
So, Your Final Answer would be A = l²/2
Hope this helps!
Tell whether each question can be written in the form y = mx + b
y = 8 - x^2 NO
y = 4 + x YES
y = 3 - 2x YES
False, it's always on the vertex of the parabola.
Answer:
The inverse i.e f^-1 (x) is (x-1)/2
Step-by-step explanation:
The main method for finding inverse function is as follows:
We let y =f(x), and write the function as y = 2x + 1.
Next, we swap the x and y, then rearrange to make y the subject. So i.e:
x = 2y + 1 (just swapping x and y)
x - 1 = 2y
y = (x-1)/2 (solving for x).
So f^-1 (x) = (x-1)/2
