How to Find the Real Zeros of a Function

The video tutorial explains how to find the value of X when F(X)=0. It begins by introducing the problem and the goal of solving for X. The teacher demonstrates substituting zero for F(X) and solving the equation using algebraic skills. The solution is verified by plugging the value back into the equation. The tutorial concludes with a recap of the process and emphasizes the importance of setting F(X)=0 to find the X values.

What is the main goal when F(X) = 0 in an equation?

• To find the value of F(X)

• To find the value of X

• To find the value of Y

• To find the value of the equation

What is the first step in solving the equation 0 = 3X - 4/5?

• Add 4 to both sides

• Multiply by 5 to eliminate the fraction

• Subtract 4 from both sides

• Divide by 3

After eliminating the fraction in the equation, what is the next step?

• Add 4 to both sides

• Subtract 4 from both sides

• Divide by 5

• Multiply by 3

What is the value of X when F(X) = 0 for the equation 0 = 3X - 4/5?

• 1/3

• 5/4

• 4/3

• 3/4

How can you verify the solution X = 4/3 in the equation?

• By substituting F(X) = 0 back into the equation

• By substituting F(X) = 4/3 back into the equation

• By substituting X = 0 back into the equation

• By substituting X = 4/3 back into the equation
