How do I do this? I’m not really sure.

Step-by-step explanation:

f(x) + g(x) = 3x^2 + 2x - 1 + x^2 - 3x + 1

f(x) + g(x) = 4x^2 - x

f(x) - g(x) = 3x^2 + 2x - 1 - x^2 + 3x - 1

f(x) - g(x) = 2x^2 + 5x - 2

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
