What is a Piece-Wise Function?

A function that has a different sub-function for different intervals of the domain is called Piece-Wise Function

The functions for the different interval is

g(x)= $\rm \sqrt[3]{x+5}$ , x ≤ -4

= -x² +11 , x > -4

The value of g(-4) will be determined by using g(x)= $\rm \sqrt[3]{x+5}$

Substituting the value x = -4

g(x) = $\rm \sqrt[3]{-4+5}$

g(x) = ∛1

g(x) = 1

Therefore, The value of g(-4) is 1. The correct option is C

Susu is solving the quadratic equation 4x2 – 8x – 13 = 0 by completing the square. Her first four steps are shown in the table.In which step did Susu first make an error?

Step 1
Step 2
Step 3
Step 4

Answers

In the question "Susu is solving the quadratic equation 4x2 – 8x – 13 = 0 by completing the square. Her first four steps are shown in the table. In which step did Susu first make an error?" Susu made her first error in step 2, when she factored out 4 she is supposed to divide 8x by 4. Thus the correct expression for step 2 should be 4(x^2 - 2x) = 13 To complete the solution for the equation: 4(x^2 - 2x + 1) = 13 + 4(1) 4(x - 1)^2 = 13 + 4 4(x - 1)^2 = 17 (x - 1)^2 = 17/4 x - 1 = +/- sqrt(17/4) x = 1 +/- sqrt(17) / 2
