Answer:
y = -2
Step-by-step explanation:
The y-intercept is the y-coordinate of the point where the curve intersects (crosses) the y-axis, i.e. when x = 0.
Therefore, to find the y-intercept, substitute x = 0 into the function:
![f(0)=\sqrt[3]{0+1} -3=\sqrt[3]{1} -3=1-3=-2](https://tex.z-dn.net/?f=f%280%29%3D%5Csqrt%5B3%5D%7B0%2B1%7D%20-3%3D%5Csqrt%5B3%5D%7B1%7D%20-3%3D1-3%3D-2)
Therefore, the curve crosses the y-axis at (0, -2) and so the y-intercept is
y = -2.
