functions (easy explanation)
I have a very quick question about exponential functions. I know how to use them and apply them but I don't know how to explain why they are always positive. Does anyone know why? An example of an exponential function would be 5 to the power of x. Thank you!

Polynomiials
Find a polynomial function with real coefficients that has the given numbers as roots: 4, 0, 3, italic i a)x^4-4x^3 +9x^2-36x b)x^3-4x^2 -3x+12 c)x^3-4x^2 +3x-12 d)4x-4x^3 -9x^2 +36x My gut instinct is either b or c but I could be wrong. If it were b or c, x=0 would not work. ...

polynomial function
Please check my answers. Find the y-intercept of the polynomial function. f(x) = -x2 - 2x + 8 I got:y=8 f(x) = (x + 1)(x - 6)(x - 1)2 I got: y=-6 f(x) = -x2(x + 6)(x2 - 1) I got:y=0
