Hello Dafnemlp47vj7
The inequality for one week would be <u><em>13 = 2c + 3 </em></u>
Function and its inverse was graphed.
<u>Step-by-step explanation:</u>
y = -4x²- 2
To find the inverse function of y = -4x²- 2 we have to transform the formula to calculate x in terms of y.
y = -4x²- 2
-4x² = y - 2
x = √(y-2) / -4
Now we can change the letters to follow the convention that x is the independent variable and y is the function's value:
y = √(x-2) / -4
Now we have to draw the graph as,
It was side by side that is LHS is the function and the RHS is its inverse.
The sum of the first four composite numbers is 27. ( 4+6+8=9)
Decimal point should be moved places to the right.
