What is the graph of f(x)=x^2-2x+3
Neko [114]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=x^{2}-2x+3

This is the equation of a vertical parabola open upwards

The vertex is a minimum

The vertex is the point (1,2)

The y-intercept is the point (0,3)

The function does not have x-intercepts

see the attached figure

Population of Jacksonville was 3810 and 2010 and is growing at an annual rate of 3.5% if the growth rate continues what will the
grin007 [14]

Answer:

FV= 5,958.67 = 5,959

Step-by-step explanation:

Giving the following information:

Current population (Present Value)= 3,810

Growth rate (g)= 3.5% annual

Number of periods (n)= 13 years

<u>To calculate the future number of people (FV), we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 3,810*(1.035^13)

FV= 5,958.67 = 5,959

Consider the problem of finding the line of symmetry and vertex of the quadratic equation f(x) =x^2-8x+15 What is the error in t
Jet001 [13]
We are given the quadratic:

f(x)=x^2-8x+15, with a=1, b=-8, c=15.


We know that the x-coordinate of the vertex, which is the point where the line of symmetry passes through is 

                                  \displaystyle{  -\frac{b}{2a}.

Thus, the x-coordinate of the vertex is -\frac{b}{2a} =-\frac{-8}{2\cdot1}= \frac{8}{2}=4.

Thus, the line of symmetry is x=4.


Answer: <span>B. The line of symmetry should have been 4 instead of –4. </span>
