The nth term of an arithmetic series is calculated using the formula
nth term= a+ (n-1) d
a= -5, n =10 and nth term in this case is 13
Thus
13= -5 +(10-1)d
13= -5+9d
9d= 18
d = 2

The axis of symmetry for the graph of the function f(x) = 3x2 + bx + 4 is x = 3/2. The value of b is -9.
The function is a type of relation, or rule, that maps one input to a specific single output.
The axis of symmetry for the graph of the function
f(x) = 3x2 + bx + 4
x = 3/2 .
In order to find the b value of the vertex of ax^2 + bx + c=0
x = -b/2a
3x^2+bx+4 = 0
Given;
3/2 = vertex
-b/2(3) = 3/2
-b/6 = 3/2
-b = 18/2
-b = 9
b=-9
Thus, The value of b is -9.
