Answer:
f(x) = –|x + 3|
The -3 is inside of the absolute value, which means that the parent function has been shifted to the left by 3 units.
Since there is a negative sign outside of the absolute value, that means that the parent function has been flipped, so instead of a v-shaped graph, the function will have a Λ shape.
On the Math is Fun website, there is a function grapher and calculator. When we graph the given function, the answer is the graph shown below.
Hope this helps!
