Choose the function that shows the correct transformation of the quadratic function shifted two units to the right one unit up.

Gnom [1K]

Answer:

ƒ(x) = (x - 2)^2 + 1

Step-by-step explanation:

To make f(x) be a translation of the graph of g(x) by (h, k), write it as ...

f(x) = g(x -h) +k

You want to translate g(x) = x^2 by (2, 1), 2 units right and 1 unit up, so the function f(x) is ...

f(x) = g(x -2) +1

f(x) = (x -2)^2 +1

In math class, 4 students complete individual surveys to determine the percentage of high school teachers that have a second job

dlinn [17]

Answer:

Option D) B and C

Step-by-step explanation:

we know that

To find out the percentage of high school teachers that have a second job, divide the number of teachers that have a second job by the total number of teachers

Survey A

$\frac{28}{110}=0.2545$

Convert to percentage

$0.2545(100)=25.45\%$

Survey B

$\frac{27}{90}=0.3$

Convert to percentage

$0.3(100)=30\%$

Survey C

$\frac{21}{70}=0.3$

Convert to percentage

$0.3(100)=30\%$

Survey D

$\frac{32}{80}=0.4$

Convert to percentage

$0.4(100)=40\%$

Compare the percentages

Surveys B and C have the same percentage

therefore

Surveys B and C show proportional results, because the ratio of the number of teachers that have a second job by the total number of teachers is equal (this number is the constant of proportionality k in a proportional relationship between two variables)

The graph of the function, f(x) = - 3x2 , opens which way up or down

DiKsa [7]

I'm guessing that the 2 in that is ^2? if so, it opens down.

(x-5)(x^2+4x-2) PLEASE HELP

ANEK [815]

Answer:

Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10

Step-by-step explanation:

Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.

x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2

Simplify terms.

x^3 − x^2 − 22x + 10

I hope this helps.
