In the function y = -5x2 + 5 , the graph will open down, be shifted up 5 units, and it will be wider than the parent function y
masya89 [10]
We are considering the function y=f(x)=-5 x^{2} +5

the graph of this function is the graph of the parent function y=g(x)= x^{2} after applying the following steps.

1. multiply by -1:

-x^{2} is x^{2} reflected with respect to the x-axis.


2. multiply by 5:

-5x^{2} is -x^{2} shrinked towards the y axis. 

for example, consider x=1/2

 -5x^{2}=-5( \frac{1}{2} )^{2}=-5* \frac{1}{4}= \frac{-5}{4}=-1.25

 -x^{2}=- ( \frac{1}{2} )^{2}=- \frac{1}{4}=-0.25

now this means that -5x^{2} is "lower" than -x^{2}, which means there is a shrinking of the graph.

3. add 5:

-5 x^{2} +5 is -5 x^{2} shifted 5 units up.


4.

so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function

Examine the diagram and information to answer the question. Rectangle EFGH has vertices at E(7,7), F(1,5), G(2,2), and H(8,4). H
schepotkina [342]

Answer:

Perimeter of rectangle = 6√10 units (the attachment isnt clear. It seems the answer is in option B)

Step-by-step explanation:

First we find the distance of the length and width of the rectangle.

Distance between E and F = Distance EF

Distance EF = √(∆y²-∆x²)

= √[(5-7)² + (1-7)²] = √[(-2)² + (-6)²]

= √(4+36) = √40

Distance EF = 2√10

Distance between F and G = Distance FG

Distance FG = √(∆y²-∆x²)

= √[(2-5)² + (2-1)²] = √[(-3)² + (1)²]

= √(9+1) = √10

Distance FG = √10

Length= distance EF = distance HG

And width = distance FG = distance EH

Perimeter of rectangle = 2(length + width)

Perimeter of rectangle = 2(2√10 + √10)

= 2(3√10)

Perimeter of rectangle = 6√10 units (the attachment isnt clear. It seems the answer is in option B)

Evgen [1.6K]

Answer:

  • Degree 3,
  • Trinomial

Step-by-step explanation:

Given

Polynomial x²-x³+ y²x

It has 3 terms, therefore is trinomial

<u>Its degree:</u>

  • x² = degree 2
  • x³ = degree 3
  • y²x = degree 2+1 = 3

Its degree is 3 as the greatest degree of its terms
