How can exponents you find the area of a rectangle if each side length is multiplied by x?

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

If f(x)=x+7 and g(x)=1/x what is (fog)(x)

Find the directions in which the function increases and decreases most rapidly at upper p 0p0. then find the derivatives of the function in these directions. f(x, y)equals=x squared plus xy plus y squaredx2+xy+y2, upper p 0p0left parenthesis 1 comma negative 4 right parenthesis
