<h3>
<u>Explanation</u></h3>
f(a) means the value of f(x) is ... when x = a. That means if we substitute x = 3, we would get f(3).
f(3) also means the value of f(x) is ... when x = 3.
f(x) can also be defined as y // f(x) = y
You can find the value of f(x) at specific domain from the graph by looking at x = 3 then look up to where the point or where the graph passes. From the graph, when x = 3 as we look up and the graph passes y-coordinate at 1.
Therefore we can say that when x = 3, y = 1.
<h3>
<u>Answer</u></h3>
f(3) = 1
1a) no it would be 54
1b) yes
1c) yes
1d) no it would be 40
1e) yes
hope this helped
The area of a rectangle is base * altitude, and the perimeter is 2*base + 2*altitude,
base = 10cm and altitude = 7cm
1/2 or 50%
cuz there’s only two probable outcomes
