Question

Calculate the range for the equation y = -2x -2, given the domain {-3, -1, 4}.


Answer
{4, -4, 6}
{-8, -4, -10}

{4, 0, -10}

{4, 0, 6}

Answer 1

you have y = -2x -2, now start putting each value from this set {-3, -1, 4}. in y = -2x -2, in the place of x. and see what you get for y. that is range
