Which is the graph of f(x) = x- - 2x + 3?

irst, solve for two points which solve the equation and plot these points:

First Point: For  

x

=

0

f

(

)

=

(

−

2

⋅

)

−

3

f

(

)

=

−

3

f

(

)

=

−

or  

(

,

−

)

Second Point: For  

x

=

−

2

f

(

=

(

f

=

f

(

2

)

=

1

or  

(

−

2

,

)

We can next plot the two points on the coordinate plane:

graph{(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(y + 2x + 3)(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}

Step-by-step explanation:

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
