The diameter of a circle is 6 ft. Find its area to the nearest tenth

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

When i add money am i supposed to make it like this 7+12 or 7.00+12.00 because i got 19 dollars for my answer

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
