Good at math,
which function and domain could represent the given graph?
a. f(x) = 1 – ⌊x⌋; –3 < x < 3
c. f(x) = –⌊x⌋; –3 ≤ x ≤ 3
d. f(x) = ⌊x⌋; –3 < x < 3

Graph red beads cost $1 an ounce and gold beads cost $3 an ounce. juanita wants to purchase a 12-ounce mixture of red and gold beads that she can sell for $2 an ounce. the solution of the system shows the number of beads needed for juanita to break even. x + y = 12, x + 3y = 24 how many ounces of red beads will juanita buy to break even? how many ounces of gold beads will she buy?

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)
