Answer:
B.) y = x² + 3, x < 4
x + 4, x ≥ 4
Step-by-step explanation:
Remember, the x-values associated with closed dots are not included in the function. Therefore, only greater than/less than signs can be applied to these points.
The exponential function includes all x-values before x = 4. Therefore, the domain for the parabola is x < 4.
The linear function includes all x-values after and including x = 4. Therefore, the domain for the linear portion of the function is x ≥ 4.
