How to find the algebraic expression that matches the graph?</h3>
On the graph, we can see an absolute value equation, which opens downwards, and passes through the points (1, 0) and (0,1).
The general absolute value equation is:
y = a*|x - b| + c
Because the vertex is at the point (0, 1), we know that:
b = 0, c = 1
Replacing that we get:
y = a*|x| + 1
Now, this must be zero when we evaluate in x = 1, then:
0 = a*|1| + 1
a = -1
Then the graphed equation is:
y = -|x| + 1

Answer: 4) 8
Step-by-step explanation:
-80/10=-8
-8 = - 8. - No
80/-10= - 8. - 8=-8 - No
-(80/10)=-(8)=-8. - 8=-8 - No
8 - Yes.
