Question

The graph shows which inequality? The vertex is (-1,3)

Answer 1

Answer: Last Option

$y> | x + 1 | +3$

Step-by-step explanation:

First we must identify the function shown in the graph.

It is a function of absolute value whose vertex is in the point (-1, 3)

The absolute value parent function is:

$h(x) = | x |$. And it has its vertex in (0, 0)

The function shown in the graph is the function h(x) displaced 1 unit to the left and 3 units to the top.

Therefore the function shown in the graph $f(x) = h (x + 1) +3$

$f (x) = | x + 1 | +3$.

Then, the region shaded in the graph are all the values of y that are above the graph of $f (x) = | x + 1 | +3$

That is, the region is formed by all values where y is greater than $f (x) = | x + 1 | +3$

Then the inequality is:

$y> | x + 1 | +3$
