using the distributive property, marta multiplied the binomial (2x + 3) by the trinomial (x^2 + x – 2) and got the expression below.
(2x)(x^2) + (2x)(x) + (2x)(–2) + (3)(x^2) + (3)(x) + (3)(–2)
which is the simplified product?
a 2x^3+ 6x^2 – x – 6
b 2x^3 + x^2 – x – 6
c 2x^3 + 5x^2 – x – 6
d2x^3 – x^2 – 7x – 6

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
