Answer:
a) (1, 109)
Explanation:
Step 1: We need to graph the function f(x) = 3x^2 +1 from the interval (-4 to 6) on the x-axis
Step 2: Graph the function f(x) = 6, which is a horizontal line. From the interval [6, 9)
The range is nothing but the y - values.
The y values start from 1 and ends 109 at the interval -4 to 9
Here with I have attached the graph. Please have a look at it.
Thank you.
