E!! you're adding a line segment every time, it looks like. I becomes L with a horizontal line at the bottom, then you can flip it and add another line to get F, then add a third horizontal line at the bottom to get E
1. She first buys shoes for $55, so you deduct that from the original amount of $115.
2. You’re left with $60
3. Each pants are $15 each, so you do $60 divided by $15.
This should equal 4 pairs of pants
Hope this helps :D
Answer:
f(x) = 3x² + 6x + 1
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Expand by FOIL (First Outside Inside Last)
- Standard Form: f(x) = ax² + bx + c
- Vertex Form: f(x) = a(bx + c)² + d
Step-by-step explanation:
<u>Step 1: Define function</u>
f(x) = 3(x + 1)² - 2
<u>Step 2: Find Standard Form</u>
- Expand by FOILing: f(x) = 3(x² + 2x + 1) - 2
- Distribute 3: f(x) = 3x² + 6x + 3 - 2
- Combine like terms (constants): f(x) = 3x² + 6x + 1
Answer:
i'm pretty sure f(x) = g(x)
Step-by-step explanation:
Let x be a variable, and f(x) a function of that variable.
f(2) is a <em>number </em>; it's the value of the function f(x) when x = 2, assuming that value exists.
f(x) = 2 is a <em>statement </em>; it says there is some value of x for which the function returns a value of 2. Because it's a statement, it can be true or false.
Here's an example:
Define f(x) = sin(x). Then f(2) = sin(2) ≈ 0.909297.
If x is a real number, then the statement sin(x) = 2 is false, because -1 ≤ sin(x) ≤ 1 for all real x.
If we replace 2 with 1, on the other hand, we get
f(1) = sin(1) ≈ 0.84147
and
sin(x) = 1 ==> x = π/2 + 2nπ
where n is any integer. (So we're talking about numbers like π/2, -3π/2, 5π/2, -7π/2, and so on.) We're saying here that any real number x of the above form satisfies the equation and makes the statement true.
