How do I graph a rational function with a y intercept. Example 3x^2-1/2x+4 +1

1 answer:

3 0

Basically see where it intersectst the y axis
that is where x=0
so set x=0 and solve
3(0)^2-1/2(0)+4+1
4+1
5
the y intercept is at y=5, so yo uknow that (0,5) is on the graph

The length of a rectangle is 4cm more than three times its width. If the

kotegsom [21]

Answer:

22cm by 6cm

Step-by-step explanation:

Width = x

Length = 3x + 4

x + x + 3x + 3x + 4 + 4 = 8x + 8

Perimeter = (8x + 8) cm

56 - 8 = 48cm

48/8 = 6

6 = x

Width = 6cm

Length = 22cm

Which transformations are needed to change the parent cosine function to<br> y = 0.35cos(8(x-pi/4))

Levart [38]

Here's a list of the changes and their effect:

$\begin{array}{c|c|c}\text{From}&\text{To}&\text{Effect}\\\cos(x)&\cos\left(x-\frac{\pi}{4}\right)&\text{Horizontal shift}\\\cos\left(x-\frac{\pi}{4}\right)&\cos\left(8\left(x-\frac{\pi}{4}\right)\right)&\text{Horizontal compression}\\\cos\left(8\left(x-\frac{\pi}{4}\right)\right)&0.35\cos\left(8\left(x-\frac{\pi}{4}\right)\right)&\text{Vertical compression}\end{array}$

So, the function is shifted $\frac{\pi}{4}$ units to the right, then it is compressed by a factor 8 horizontally, and a factor 0.35 vertically.
