F(x) = x^2 - x + 2
f(x) = x^2 - x + 1/4 + 2 - 1/4
f(x) = (x - 1/2)^2 + 7/4
Therefore, vertex = (1/2, 7/4)

Consider the following expression: (1 + x)^n. A) Use the Binomial Theorem to find the first four terms of this polynomial. B) Wh
sergiy2304 [10]
Given:

The expression:  (1 + x)^n

The Binomial Theorem is used to predict the products of a binomial raised to a certain power, n, without multiplying the terms one by one. 

The following formula is used:

(a + b)^n = nCk * a^(n-k) * b^k

we have (1 +x)^n,

where a = 1 
            b = x
let n = 4

First term, k = 1

4C1 = 4

first term: 4*(1^(4-1))*x^1

Therefore, the first term is 4x. Do the same for the next three terms. 

2nd term: k =2 
3rd term: k = 3
4th term: k = 4

3n + 14= --4 What is the answer
andre [41]

Answer: n = -6

Step-by-step explanation:

3n+14=-4

Subtract 14 from both sides.

3n+14-14=-4-14

Simplify

3n=-18

Divide both sides by 3

3n/3 = -18/3

n=-6

How to graph this! Thank you
matrenka [14]

Answer:

Step-by-step explanation:

Yay graphs!!!!!!

Okay so as you should know, the structure of a linear equation is y = mx + b.

B is the y-intercept

so the first thing to do is mark the coordinates (0,1) as the y-intercept

Now the slope is 1/4 x

this is also known as rise/run

A simpler way to do that is from (0,1) move up 1 and over four and place a point there

The coordinate should be (4,1)

Then draw a line through the two points
