Which of the graphs shown is given by the equation y = x^2 + 3?
- a
- b
- c
Explanation from PART66Online
y = x^2 + 3 is a quadratic, so its graph is a U-shaped parabola, and the +3 lifts its lowest point to y = 3 on the y-axis: graph c. The straight line is a linear equation (y = 2x + 3), and the S-shaped curve is a cubic.

First graph is cosinus function, middle is linear y=ax+b something more like (y=3/2x+3) enter it to Google to check, and the last one is parabola (square function) y=ax^2+bx+c which here is simplified to form y=ax^2+b look up to khanacadamy.com
