Original function:
y = 2x - 6
To find the inverse function, swap the x and y variables and then solve for y:
x = 2y - 6
Add 6 to both sides:
x + 6 = 2y
Divide both sides by 2:
y = (x + 6)/2
That's the inverse function:
f⁻¹(x) = (x + 6)/2
y = 2x - 6
To find the inverse function, swap the x and y variables and then solve for y:
x = 2y - 6
Add 6 to both sides:
x + 6 = 2y
Divide both sides by 2:
y = (x + 6)/2
That's the inverse function:
f⁻¹(x) = (x + 6)/2
