**Precalculus with applications**

f(x)=-4x^2 g(x)=2/x so g(f(x))= 2/(-4x^2)=-1/2x^2 I am wondering why you titled this Precalculus with applications? This problem is certainly content for algebra II. Is someone playing with course names again?

I just realized that the equation that relates x and y to the total length of material should be 2y + 4x = 600. You need 4 fence segments of length x to create 3 areas. Therefore, y = 300 - 2x A = x*(300 - 2x) = 300x - 2x^2 Since dA/dx = 0, 4x = 300 and x = 75. y = 150 Maximum...

You need to combine like terms. Numerals cannot be combined with X terms. 3x/x+1=12/x^2-1+2 x/x cancel each other out. 3 + 1 = 12/x^2 + 1 Subtract 1 from each side. 3 = 12/x^2 Multiply both sides by x^2. 3x^2 = 12 Divide both sides by 3. x^2 = 4 x = 2 Possibly these sources ...
