If (he)={(0,1),(2,3),(-4,1)}, find h^-1(x)

The given function is

The inverse function is

To get the inverse, we swap each x and y coordinate.

The rule is

So that's why the point (0,1) becomes (1,0) for instance.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

current in the circuit at time t is /, then the power delivered to the resistor is
