The graph shows g(x), which is a translation of f(x) = x^2. Write the function rule for g(x). Show step by step.

Mariana [72]

Answer:

$g(x)=(x-7)^2+6$

g(x) is a translation of f(x) 7 units to the right and 6 units up.

Step-by-step explanation:

Let the equation of the function g(x) be

$g(x)=a(x-b)^2+c$

This curve passes through the points (9,10), (5,10) and (7,6), then their coordinates satisfy the equation:

$10=a(9-b)^2+c\\ \\10=a(5-b)^2+c\\ \\6=a(7-b)^2+c$

Subtract the second equation from the first:

$10-10=a(9-b)^2+c-a(5-b)^2-c\\ \\0=a((9-b)^2-(5-b)^2)\\ \\a\neq 0\ \text{then}\ (9-b)^2-(5-b)^2=0\\ \\(9-b)^2=(5-b)^2\\ \\9-b=5-b\ \text{or}\ 9-b=b-5\\ \\9=5\ \text{false}\\ \\2b=14\\ \\b=7$

Then

$10=a(9-7)^2+c\\ \\6=a(7-7)^2+c$

So,

$10=4a+c\\ \\6=c$

Hence,

$c=6\\ \\b=7\\ \\10=4a+6\Rightarrow a=1$

The expression for g(x) is

$g(x)=(x-7)^2+6$

g(x) is a translation of f(x) 7 units to the right and 6 units up.

Alinehasaslopeof 1/3 anda y-intercept of –5What isitsequationin slope-intercept form? Write your answer using integers, proper f

user100 [1]

Answer:

$y = \frac{1}{3}x - 5$

Step-by-step explanation:

Given

$slope\ (m) = \frac{1}{3}$

$y\ intercept = -5$

Required

Determine the line equation in slope intercept

The equation of a line in slope intercept is:

$y = mx + b$

Where

$m = slope = \frac{1}{3}$

$b = y\ intercept = -5$

So, $y = mx + b$ becomes

$y = \frac{1}{3}x - 5$

To draw a line segment perpendicular to XY passing through point x

Andrew [12]

What does perpendicular mean? Well, in elementary geometry it mean 2 lines that intersect at a right angle. (90°).

So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M.

Now you will connect the line M and Z.

Thats it! I hope this helped!! :)
