Question

Consider the function 𝑓(𝑥) = −√36 − 𝑥^2

a) Use GeoGebra to draw the graph of 𝑓.
• Open GeoGebra
• Define the function. Beside the + button, begin typing in the “Input…” box by typing
f(x) = –sqrt(36 – x^2)

b) Evaluate the function when 𝑥 = 1. Report the answer as a decimal.
• In the next line, type f(1) to substitute the value of 𝑥 = 1 into the function.
• Press the ≈ button beside the output to turn your answer into a decimal.
You will attach a single screenshot of your GeoGebra sheet which shows part a) and part b).

c) From the graph, identify the domain and range of 𝑓.

d) From the graph, identify the interval(s) of increase and decrease of 𝑓.

Answer 1

Geesh!

First of all, don't assume that everybody uses the GeoGebra software
I looked it up, tried to use it, and found it rather user-unfriendly.

Anyway, the instructions for you for very clear, why did you not follow
them?
What part could you not do?

I graphed it, and it showed the bottom half of a circle with radius 6
