College Algebra Practice Problems Questions and Answers 2023 Factor: 9y^2 + 36y + 35 (3y+7)(3y+5) Linear or non-linear? 6/x + 14 = 40 Non-linear y = 2x - 3 This is linear because the exponent on x is one. Thus your slope is standard rise over run, like a stair step and simply goes up or down. Y = x^2 + x + 4 is nonlinear. When graphed it becomes a parabola, which looks like a hill on your graph. This is because the exponent on the variable of x is more than one. Solv...
