Answer:
The mapping diagram above <em><u>represents</u></em> a function since <em><u>there is one number</u></em> in <em><u>Set A (the input)</u></em> where there <em><u>is only one mapping</u></em><em><u> </u></em><em><u>to Set B (the output)</u></em>.
Step-by-step explanation:
For each number in set A, there is one mapping from set A (input) to set B (output), so the mapping represents a function.
NB. The relation is a function IF AND ONLY IF each input value has only 1 output value.

Answer:
<h2>
y = -3/2x + 9/2</h2>
Step-by-step explanation:
first let's convert the equation to y=2/3x+5
since the line is perpendicular we know that m=-3/2=1.5. now we just need to plug these numbers into an equation.
3=(-1.5)1+b
multiply.
3=-1.5+b
now add 1.5 to both sides of the equation.
4.5=b
change that into a fraction.
9/2.
now using 9/2 as b and -3/2 as m we have our equation:
<h2>
<u>y = -3/2x + 9/2.</u></h2>
Answer:
g(1) = 2
Step-by-step explanation:
g(x) = x^2 + 1
if x=1
g(1) = 1^2 + 1
g(1) = 1 + 1
g(1) = 2
Hope this helps!
