4) Identify the domain and range of the following graph. Provide approximate values. Note: This problem has ideas (domain of functions) for objective 4. Domain: Range: y f(x) 5) Find the zeroes of the following functions. Note: This problem has ideas (zeroes of functions) for objective 4. a) f(x)=x2-4 ANSWER: b) f(x)- -2x +10 ANSWER:

Solution

4. Domain is related to set of x values and range is related to set of y values.

Here x values are from -5 to 6 and y values are from -4 from 5.

So domain [-5,6] and range [-4,5]

5. f(x)=x²-4

Zeroes

f(x)=0

x²-4=0

x²=4

x=-2,2

b. f(x)=-2x+10

-2x+10=0

2x=10

x=5
