The graph shown above is a "parabola" and the parent function is x². So, we can start off at x². The graph of x² intersects the x and y-axis at (0, 0). In this case, it's simply being shifted up by 1 and intersects the x and y-axis at (0, 1). Therefore, the equation is:
![y = x^2 + 1](https://img.qammunity.org/2019/formulas/mathematics/middle-school/gxrzk7w4rmtptws7n2s41ivwhnlhdqak7b.png)
To check, let's plug in 0 for x, and see what we get (we should get 1):
![y = x^2 + 1](https://img.qammunity.org/2019/formulas/mathematics/middle-school/gxrzk7w4rmtptws7n2s41ivwhnlhdqak7b.png)
![y = 0^2+1 = 0+1=1](https://img.qammunity.org/2019/formulas/mathematics/middle-school/yj1rux88jd0qtg8rpprkqombd6cmavd59u.png)
We are right, so your final answer is
x² + 1.
