Answer:

y=-2/3x

Step-by-step explanation:

if you use the graphing calculator, the y intercept of the equation is 0 therefore y=mx

m=-2/3

the slope intercept equation is y=-2/3x

Answer:

$\frac{f(x+h)-f(x)}{h}$ $=2x + h$

Step-by-step explanation:

Given

$f(x)= x^2 + 2$

Required

Determine: $\frac{f(x+h)-f(x)}{h}$

First, we calculate f(x + h)

$f(x)= x^2 + 2$

$f(x+h) = (x+h)^2+2$

$f(x+h) = x^2+2xh+h^2+2$

So, we have:

$\frac{f(x+h)-f(x)}{h}$ $= \frac{x^2 + 2xh + h^2 + 2 - x^2 - 2}{h}$

$\frac{f(x+h)-f(x)}{h}$ $= \frac{x^2 - x^2+ 2xh + h^2 + 2 - 2}{h}$

$\frac{f(x+h)-f(x)}{h}$ $= \frac{2xh + h^2}{h}$

$\frac{f(x+h)-f(x)}{h}$ $=2x + h$

Which phrase best descubes the translation from the graph y = (x - 5)2 + 7 to the graph of y = (x + 1)2 - 2?

Ber [7]

Answer:

"6 units left and 9 units down"

Step-by-step explanation:

Suppose a function is given in this form:

$y=(x-a)^2+b$

This is the parent function y = x^2

translated a units right (left if there was a + before a)
translated b units up (down if there was a - before b)

Now, to go from $y=(x-5)^2+7$ to $y= (x+1)^2-2$ , we can see that:

first function is 5 units right and 2nd one is 1 unit left, so there is a horizontal translation of 6 units left
first function is 7 units above and 2nd one is 2 units down, so there is a vertical translation of 9 units down

Thus, "6 units left and 9 units down" is the transformation(translation).
