Suppose f left-parenthesis x right-parenthesis equals 1.5 x squared for negative 1 less-than x less-than 1. determine the mean and variance of x.

What can each term of the equation be multiplied by to eliminate the fractions before solving? x – + 2x = + x 2 6 10 12

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
