find the domain  f(x)=√10-x answer is (-infinity,10}

what is the end function. f(x)=120+39x+3x^2

For the function f(x)=-2^2+5x+2 find: f(-2) find: f(a+h)-f(a)

f(x)=-x^2+4x-4

The profit function for a company that produces shoes is given by y = - 2x ^ 2 + 12x +23, where "y" is the profit (in thousands of dollars) and "x" is the amount of items produced and sold (in hundreds). The maximum profit of the company will be:

If f(x) = x^2 + 7 and g(x) = Square root of x + 8,a. find and simplify (fog)(x) and write its domain in interval notation.b. find and simplify (gof)(x) and write its domain in interval notation.
