A triangle on a coordinate plane is translated according to the rule T-8.4(X, Y). Which is another way to write this rule?
O (X, Y) - (x + 4y - 8)
O (x, y) - (x - 4.-8)
O (x, y) - (x - 8, y + 4)
O (X, Y) - (x +8.y-

The answer is c

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
