Answer:
B) Vertex = (-5, 2)
Step-by-step explanation:
Vertex can be defined as defined as the point where two lines meet and form a particular angle with each other. It can also be described as the point where a line changes its direction
We can find vertex by two methods:
<h3>1) GRAPH</h3>We can see in the graph attached below that the line changes its direction at point (-5, 2). So the vertex is (-5,2)
<h3>2) FORMULA</h3>General form of equation of mod function is given by
y = a |x - h| + k
where Vertex = (h, k)
The given equation is
h(x) = 3 |x + 5| + 2
h(x) = 3 |x - (-5)| + 2
where h = -5 and k = 2
So the vertex is:
Vertex = (-5, 2)
A. 2.
A radical is an expression which implies the use of a root.
There are three components of a radical expression:
(i) The root "√".
(ii) The radicand √"a".
(iii) The degree or index of the radical , when index of the radical is not shown then it understood to be a index of 2.
The index is the number used to indicate the degree of the root.
For the example , 10 is the radican and the index is not shown so it understood is 2.
