Math Problem Statement

Select the correct answer below:

f(x)=−3|x−3|−3

f(x)=3|x−3|−3

f(x)=−3|x+3|−3

f(x)=3|x+3|−3

f(x)=−3|x−3|+3

Which of the following functions is shown in the graph below? Select the correct answer below: f(x)=−3|x−3|−3, f(x)=3|x−3|−3, f(x)=−3|x+3|−3, f(x)=3|x+3|−3, f(x)=−3|x−3|+3

Solution

The graph shows a V-shaped curve, which suggests it is an absolute value function of the form f(x)=axh+kf(x) = a|x - h| + k, where (h,k)(h, k) is the vertex of the function, and aa affects the slope and direction of the lines (whether the V opens upwards or downwards).

Key observations:

  • The vertex is at (3,3)(3, -3).
  • The graph opens downwards, meaning aa must be negative.
  • The function is shifted 3 units to the right (so the expression should be x3|x - 3|).

Analyzing the given options:

  1. f(x)=3x33f(x) = -3|x - 3| - 3 seems like a good fit, as it reflects the downward opening, the vertex at (3,3)(3, -3), and the correct transformation.
  2. The other options either have incorrect signs for aa (like the positive ones that would open upwards), or incorrect horizontal shifts (like those involving x+3x + 3).

Thus, the correct answer is:

f(x)=3x33f(x) = -3|x - 3| - 3

Tip:

When solving absolute value problems, always identify the vertex and check the direction (upwards or downwards) to quickly narrow down the correct function.
