3x + 3y = 15

2x + 3y = 13

x = 3
x = 3

x = 2
x = 2

x = 87
x = 87

x = 1

where's the diagrams?

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.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.
