Function equations the equation y=3x−5 represents a function. true false a function can only be represented by a straight line on the coordinate plane. true false what are the ordered pairs for y = 4x + 2 using x={−2,  1, 2} what is the value of the function at x=3? (see attachment) what is the value of the function y=2x−3 when x=−1? {(3, , , , 8)} is a function or is not a function {(2, , , , 4)} is a function or is not a function {(2, , , , 6)} is a function or is not a function {(3, , , , 4)} is a function or is not a function will and brainliest anyone who gives correct answers!
