Answer:
the outlier is 4
Look at all the numbers in the set:
24,18,26,20,18,24,4,24
the numbers 24,18,26,20,18,24,24 are all close in range to each other but the number 4 is not.
so therefore, the outlier is 4.
Answer:
Step-by-step explanation:
Vertex form of a quadratic is given by:
Where (h, k) is the vertex and <em>a</em> is the leading coefficient.
We are given that the vertex is (3, 1). Hence, <em>h</em> = 3 and <em>k </em>= 1. By substitution:
We are also given a point (2, -6). This means that when <em>x </em>= 2, <em>f(x)</em> = -6. Hence:
Solve for <em>a</em>. Subtract:
Simplify:
Therefore:
Hence, our quadratic is:
