Function, Domain And Range, Vertical Line Test - Quiz

Quiz Preview

  • 2. 

    F(x) = 2x+5Evaluate f(3).

    • 10

    • 11

    • 12

    Correct Answer
    A. 11
    Explanation
    To evaluate f(3), we substitute 3 into the equation f(x) = 2x + 5. This gives us f(3) = 2(3) + 5 = 6 + 5 = 11. Therefore, the correct answer is 11.

    Rate this question:

  • 3. 
    Is this a function? - ProProfs

    Is this a function?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    The given question asks if something is a function. The answer provided is "No". This means that the thing in question is not a function.

    Rate this question:

  • 4. 

    F(x) = x^3-xEvaluate f(4).

    • 48

    • 60

    • 40

    Correct Answer
    A. 60
    Explanation
    To find the value of f(4), we substitute 4 into the function f(x) = x^3 - x. Therefore, f(4) = 4^3 - 4 = 64 - 4 = 60.

    Rate this question:

  • 5. 

    Which does NOT represent a function from A to B?

    • {(0,1),(1,-2),(2,0),(3,0)}

    • {(0,-1),(1,-2),(2,2),(3,0),(1,1)}

    • {(0,0),(1,0),(2,0),(3,0)}

    Correct Answer
    A. {(0,-1),(1,-2),(2,2),(3,0),(1,1)}
  • 6. 
    Is the relationship a function? - ProProfs

    Is the relationship a function?

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    The relationship is a function because for every input, there is only one corresponding output.

    Rate this question:

  • 7. 

    F(x) = x^2 – 5x + 4Evaluate f(8).

    • 20

    • 24

    • 28

    Correct Answer
    A. 28
    Explanation
    To evaluate f(8), we substitute x=8 into the given function f(x). So, f(8) = 8^2 - 5(8) + 4 = 64 - 40 + 4 = 28. Therefore, the correct answer is 28.

    Rate this question:

  • 8. 

    F(x) = 4x^2Evaluate f(5).

    • 100

    • 400

    • 81

    Correct Answer
    A. 100
    Explanation
    To evaluate f(5), we substitute 5 into the function f(x) = 4x^2. Therefore, f(5) = 4(5)^2 = 4(25) = 100.
