If a function rule is 2x – 3, what is the output for the input 3?
2 answers:
Answer:
The function rule can be written as: f(x) = 2x-3
So, when we input 3, we replace all of the x's for 3's and have: f(3) = 2(3)-3.
This simplifies to be: f(3) = 3, meaning that 3 is the output.
Hope this helps!
Answer:3
Step-by-step explanation:
The output value is y so set an equation at y=2x-3. Now x is the input value so plug in 3 for x. Two times three is 6 and then you have to subtract three from that. So the output value for an input of 3 is 3.

Answer: 3/20 of the class
Step-by-step explanation:
Add the amount of students that play soccer to amount of students that play volleyball
1/4 + 3/5 = 17/20
Subtract 17/20 (soccer and volley ball) from 20/20 or 1
20/20 - 17/20 = 3/20
