part as a decimal:

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

The sum of two numbers is 86, and their difference is 20. find the two numbers

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
