Answer:
-4x² - 2xy + 5y²
Step-by-step explanation:
Step 1: Write expression
(3x² - 5xy + 2y²) - (7x² - 3xy - 3y²)
Step 2: Distribute negative
3x² - 5xy + 2y² - 7x² + 3xy + 3y²
Step 3: Combine like terms
-4x² - 2xy + 5y²
To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.
Original equation:
y = 4x + 5
Switched:
x = 4y + 5
Solve for y by isolating it:
x - 5 = 4y + 5 - 5
x - 5 = 4y
(x - 5)/4 = 4y/4
