Graph the function. f(x)=2x^2-5<br> please help ill give you brainliest
snow_lady [41]

f(x)=2x^2+0x-5

Find the vertex

0/4=0=x

Input x into the equation to find y or f(x)

0+0-5=f(x)

(0,-5) = Vertex

Now find a random x coordinate to input into the equation.

Let's do 4.

32+0-5=f(x)=27

It may not look like a parabola due to it being uneven.

Svetllana [295]
In this item, it is assumed that since the pattern is cut out of the paper which is usually a rectangle then, the shape of the pattern is also rectangle. The perimeter of the rectangle is,

           P = 2L + 2W

The area is equal to,
              Area = L x W

If we assume that length and width are equal, in order to maximize the space. 
              1600 cm² = L x L

The value of L from the equation is 40 cm.

riadik2000 [5.3K]

Answer:

Dharma and Jorge should purchase a group plan.

They could save $9.55

Step-by-step explanation:

A group plan will cost an average of $135.95 per month.

An individual plan will cost an average of $72.75 per month.

Two individual plans will cost an average of

\$72.75\cdot 2=\$145.50

per month.

Since $145.50 > $135.95,  Dharma and Jorge should purchase a group plan.

They could save

\$145.50-\$135.95=\$9.55
