The value of (fg)(x)= 3x³+ x²
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given:
f(x) = -3x+1
g(x) = 
Now, (fg)(x)
=f(x) * g(x)
= (-3x+1) * ()
=-3x³+ x²
Hence, (fg)(x)= 3x³+ x²

Answer:
y = (x-0)^2 + (-5) ⇒ y = x^2 - 5
Step-by-step explanation:
The general vertex form of the parabola y = a(x - h)² + k
Where (h,k) is the coordinates of the vertex.
As shown at the graph the vertex of the parabola is the point (0, -5)
So,
y = a(x-0) + (-5)
y = ax^2 - 5
To find substitute with another point from the graph like (1,-4)
So, at x = 1 ⇒ y = -4
-4 = a * 1^2 - 5
a = -4 + 5 = 1
<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>

Given :
Plan A will cost $2.00 per song. Plan B will require a $15 joining fee and $1.49 per song.
To Find :
When will Plan A be a less expensive option for Aubrey? When will Plan B be a less expensive option for Aubrey?
Solution :
Let, after x songs Plan A will be less expensive.
So,
2x < 15 + 1.49x
0.01x < 15
x < 29.41 i.e x < 30
Before, 30 songs Plan A will be less expensive.
After, 30 songs Plan B will be less expensive.
Hence, this is the required solution.
