Find dx/dt at x=-2 and y=2x^2+1 if dy/dt=-1 Round your answer to 3 decimal places.
Because the task contains expressions `dx / dt` and `dy / dt,` we know that `x` and `y` are functions of `t :`
`x = x ( t ), y = y ( t ) .`
Here `t` is an independent variable.
Also, an equation that connects `x` and `y` is given:
`y = 2 x ^ 2 + 1 .`
