Question

Choose the equation for the graph.1a) y = -1x – 41 + 1b) y = -1x – 41 - 1c) y = -x +41 +1d) y = -x +41 - 1e) y = |x - 41 +1

Answer 1

From the graph we can see that,

for

x = 0, y = -5

x = 1, y = -4

And so on

So we can write,

`-4=-\mleft|1+4\mright|+1`

That is,

`y=-\mleft|x+4\mright|+1`

The answer is option c.
