Consider the polynomial 3x3 + 9x2 − 12x. Select the True or False for each statement.

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?

The suare root of 9x plus 7 plus the square rot of 2x equall to 7
