Algebra 1 which expressions are polynomials? a. z+1 b. 6+w c. 2x^4-y d. y^2−3√y+4 (the 3 is above? ? i cant format it)

Example C: w cubed z, +, 5, z squared, minus z squared, +, 6 For example, 2x + 1 = 7x and 10x minus 9y minus z = 3 are linear equations, but x, +, y ...

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.
