Answer:
-(-1) = 1 And Vice Versa
Step-by-step explanation:
Two Negatives cancel each other out. So, -(-1) have the multiplication of 2 negatives, which results in a positive 1.
Answer: 4. No, the graph is NOT a function because using the vertical line test, it intersects at two points at a time.
5. Yes, it is a relation, and it is also a function because once those points are plotted if given the vertical line test, there would not be two points crossed at once. So, yes, it is a function.
6. Yes, it is a relation. No, it does NOT make up a function because a vertical line would intersect all the points given.
Y = 3√(x-1).
Constraint: the radicand (x-1) ≥ 0 or x≥ 1
So the domain of this function is all Real for x ≥ 1
{x∈ R/x≥1}
X/4=2 and 1/4
comvert 2 and 1/4 to impropoer fraction
2 and 1/4=2+1/4=8/4+1/4=9/4
x/4=9/4
multiply both sides by 4
x=9
It should be d because u have to estimate and finds the y intercept
