Respuesta :

the minimum is (0,4)

the y intercept is (0,4)

there isn't an actual solution

Step 1: Subtract 4 from both sides.

81x^2+4=0

81x^2=-4

Step 2: Divide both sides by 81.

81x^2/81=-4/81

x^2=-4/81

Step 3: Take square root.

x=±[tex] \sqrt{\frac{-4}{81}} [/tex]

Answer: No real solutions.
