General Formulas and Concepts:

Algebra I

Composite Functions
Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = 4x² + 1

g(x) = x² - 5

(f + g)(x) is f(x) + g(x)

Step 2: Find (f + g)(x)

Substitute: (f + g)(x) = 4x² + 1 + x² - 5
Combine like terms: (f + g)(x) = 5x² - 4

Find the value of x.

Paul [167]

Hello!

As we are looking for the opposite side and hypotenuse, we will use the sine.

sin30=1/2

This gives us the equation below.

1/2= 5/x

1/2x=5

x=10

Therefore, x=10.

I hope this helps!

Identify the parent function that can be used to graph the function f(x)=3(x-9)2

dmitriy555 [2]

Answer: f(x) = x²

Step-by-step explanation:

The vertex form of a quadratic equation is: f(x) = a(x - h)² + k where;

|a| is the vertical stretch
-a is a reflection across the x-axis
(h, k) is the vertex

The parent function is where a = 1 and the vertex is at the origin (h, k) = (0, 0)

→ f(x) = 1(x - 0)² + 0

⇒ f(x) = x²
