Question

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

Answer 1

Answer:

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

First Point: For  

x

=

0

f

(

0

)

=

(

−

2

⋅

0

)

−

3

f

(

0

)

=

0

−

3

f

(

0

)

=

−

3

or  

(

0

,

−

3

)

Second Point: For  

x

=

−

2

f

(

−

2

)

=

(

−

2

⋅

−

2

)

−

3

f

(

−

2

)

=

4

−

3

f

(

−

2

)

=

1

or  

(

−

2

,

1

)

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]}
