Question

Use the image to answer the question.

Two V-shaped curves are graphed on a coordinate plane. The x-axis ranges from negative 3 to 3 in increments of 1. The y-axis ranges from negative 5 to 5 in increments of 1.

The graph shows a parent function as a solid line and the translated function as a dotted line. Describe the effect the transformation has on the equation of the parent function f(x)=|x|
by determining the value of k in the translated function.

(1 point)
The value of k in the translated function is f(x)=|x|+

.

Answer 1

I can’t see the image you referenced. To find k in f(x) = |x| + k you only need the vertical shift — the y-coordinate of the translated V’s vertex.

Tell me the vertex of the dotted (translated) graph (for example (0,2) or (0,−3)), or upload the image, and I’ll give the value of k.

(If you want to do it yourself: locate the vertex of the dotted V; if it is at (0,k) then the transformed function is f(x)=|x|+k.)
