Help with quadratic graphs asap!
zlopas [31]

x= -0.25 and 1.25

x = -0.5 and  1.5

x = 0 and 1

x = -0.375 and 1.625

Step-by-step explanation:

Given equation of the curve is

y = 4x^2 -4x-1

(i)

First equation 4x^2 -4x-1 =0

Here y = 0

In  x-axis the value of y = 0

The graph cuts the x-axis at(-0.25,0) and (1.25,0)

So, x= -0.25 and 1.25

(ii)

4x^2 -4x-1 =2

here y = 2

The line y= 2 cuts the curve at (-0.5,2) and (1.5,2)

So, x = -0.5 and  1.5

Given equation of the curve is

y= 3x^2-3x -1

(i)

3x^2-3x +2 =2

\Leftrightarrow  3x^2-3x -1 = -1

Here y = -1

The line y = -1  cuts the curve at (0,-1) and (1,-1)

So x = 0 and 1

(ii)

3x^2-3x -1 =x+1

Here y = x+1

The line y -x =1 cuts the curve at (-0.375,0.5) and (1.625,2).

So x = -0.375 and 1.625

Helppppp plzzzzzzzz<br> No links please and thank you .

Answer:

for the first picture: 2.16

Step-by-step explanation:

12% of 18 is 2.16:

-convert 12 % to a decimal so 0.12 times 18

also, 12 % percent is 0.12 as a decimal because you move the decimal 2 places to the left to get .12

- multiply 0.12 times 18 to get 2.16 as the answer

I hope this helped for the first pic!
