Learn how to evaluate a linear function

The video tutorial demonstrates how to evaluate the function F of X = -4X + 6 at 2C. It begins by explaining the function and the process of substituting values into it. The tutorial then guides viewers through the steps of plugging in 2C for X, performing the necessary calculations, and arriving at the final result, F of 2C = -8C + 6.

What is the general form of the function discussed in the video?

• F(x) = 4x + 6

• F(x) = -4x + 6

• F(x) = -4x - 6

• F(x) = 4x - 6

What is the first step in evaluating F(2C) for the function F(x) = -4x + 6?

• Divide the function by 2C

• Substitute 2C for x in the function

• Multiply the function by 2C

• Add 2C to the function

After substituting 2C into the function, what is the expression obtained before simplification?

• 4 + 2C + 6

• 4 * 2C + 6

• -4 + 2C + 6

• -4 * 2C + 6

What is the simplified form of F(2C) after substitution and calculation?

• 8C - 6

• 8C + 6

• -8C - 6

• -8C + 6

Which of the following is the correct final answer for F(2C)?

• F(2C) = 8C + 6

• F(2C) = 8C - 6

• F(2C) = -8C - 6

• F(2C) = -8C + 6
