Find the domain of the graphed function. 10-
-10
-10
A. -9 sxs 5
B. O sxs 10
C. x is all real numbers.
D. x20

The left most point is (0,0). We see that x = 0 is the smallest allowed input in the domain. Any other larger x value is allowed. This extends on to positive infinity. So x is either 0 or larger than 0, and we write as the domain of possible x value inputs.

m∠a is 90°

m∠b is 40°

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
