Evaluating Functions: Level 1 Challenge

What is the function given in the first example?

• f(x) = 2x + 3

• g(x) = 3x - 4

• k(x) = x^2 - 1

• h(x) = 4x - 5

What value of x are we asked to find in the first example?

• h(2)

• h(3)

• h(4)

• h(1)

What is the first step in evaluating h(2) for the function h(x) = 4x - 5?

• Add 5 to 4x

• Multiply 4 by 2

• Subtract 5 from 2

• Divide 4 by 2

What is the result of 4 times 2 in the evaluation of h(2)?

• 10

• 8

• 6

• 12

What is the final result of h(2) for the function h(x) = 4x - 5?

• 1

• 4

• 2

• 3

What does the result h(2) = 3 signify?

• When x is 2, the output is 3

• When x is 4, the output is 1

• When x is 1, the output is 4

• When x is 3, the output is 2

What is the function given in the second example?

• h(x) = 4x - 5

• g(x) = 3x - 4

• k(x) = x^2 - 1

• f(x) = 2x + 3

What value of x are we asked to find in the second example?

• g(4)

• g(2)

• g(3)

• g(1)

What is the first step in evaluating g(1) for the function g(x) = 3x - 4?

• Add 4 to 3x

• Multiply 3 by 1

• Subtract 4 from 1

• Divide 3 by 1

What is the final result of g(1) for the function g(x) = 3x - 4?

• 2

• Negative 1

• 0

• 1
