Plz help I will be giving extra 50 points
2 answers:
it isn't possible to just give extra points in a simple and reliableway. anyways, let's starts.
a. is simple, just put the terms in order
r² +6r -5
because:
anything to the power of 0 equals 1,
because it's the same as r/r, and 5 * r/r = 5*1
b. same logic as above
a²b² -5ab +33
c.
-c³ +ab +d +9
d.
-9y^5 - 2x³y²z +4x² +10x +1
^5 = to the power of five, it's the fastest way to type it without the special math input tool.
hope it helps you

Answer:
Domain = {3,4,9}
Range = {2, 6, 8, 9.5}
Given relation is NOT a function.
Step-by-step explanation:
Given relation is relation is ((9,6), (3,8),(4,9.5), (9,2)}.
Now we need to determine if given relation is a function or not.
We also need to find the domain and range.
((9,6), (3,8),(4,9.5), (9,2)}
Domain is basically the collection of x-values
So Domain = {3,4,9}
Range is basically the collection of y-values
So Range = {2, 6, 8, 9.5}
Since given relation contains repeated x-value "9".
So the given relation is NOT a function.
