Step-by-step explanation:
x = domain, f(x) = range
<u>Look for matching numbers:</u>
Answers:
f(4) is 1/2
f(x) = 4 when x is 8
====================================
Explanation:
Saying f(4) means f(x) when x = 4.
Locate 4 in the domain bubble. It points to 1/2 in the range bubble. This means x = 4 and y = 1/2 pair up. So f(4) = 1/2.
--------
When we're told f(x) = 4, we're given that y = 4 since y = f(x). So we need to find the x value that gets us to y = 4.
Locate y = 4 in the range. Trace the arrow in reverse to get to x = 8
f(8) = 4

Range = biggest value - smallest value
9-6 = 3
