Answer:
f(-1) = 3
Step-by-step explanation:
f(-1) means the value of y at x = -1.
So what's the value of y at x = 1?
First, focus on the graph and look at x = -1.
Next, see which y-value does graph pass through when x = -1.
Looks like the graph passes y = 3 when x = -1
Thus, f(-1) = 3
The percentage increase of tvs sold ilfrom 50 and 60 is 20%
<h3>What is percentage increase?</h3>
percentage increase can be regarded as the
relative change and relative difference used in comparing two quantities.
The percentage increase can be calculated as;
[50/100] = [60/x]
if we cross products, we have
[50x]=[6000]
Then
x=120
Therefore, 60 is 120% of 50
Then the percentage increase of tvs sold ilfrom 50 and 60 is 20%
