Determine if the expression –7w5 +w3 – 7w2 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomimal.

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. answer to the nearest integer.
