Answer: f(x) = 4 if -1 ≤x ≤ 1
f(x) = x - 1 if 3≤ x ≤ 5
Step-by-step explanation:
if -1 ≤x ≤ 1
We can see that in this range the function is constant, f(x) = 4
if 3≤ x ≤ 5
In this region we can see a linear relationship, with the points (3, 2) and (5, 4)
as the extremes, we can find the slope of this linear equation as:
s = (4 - 2)/(5 - 3) = 2/2 = 1
So our equation is
f(x) = 1*x + b
to find the value of b we can evaluate our function in the first point, we know that when x = 3, y = 2, so we have:
2 = 1*3 + b
b = 2- 3 = -1
then f(x) = 1*x - 1
Then we have:
f(x) = 4 if -1 ≤x ≤ 1
f(x) = x - 1 if 3≤ x ≤ 5
5.56 is your answer because you multiply 2.78 times 2 to get the absolute value.
Answer:
It can be written. You have to write the converse and conditional first.
Conditional: if two angles are congruent, then they have the same measure.
Converse: if two angles have the same measure, then they are congruent.
Both these statement have to be correct or write a biconditional.
Biconditional: two angles are congruent if and only if they have equal measures.

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, </em><em>b</em><em>)</em>
<em />
The fromual of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - points on a line</em>
<em />
We have the points from the graph:
(0, 1) → <em>b = 1</em> and (3, 3).
Calculate the slope:
Finally we have the equation of a line:
