I’m confused on how to graph three and four at the top

1 answer:

8 0

You already graphed 3 and 4, 3 is the one you have graphed on the top and 4 is the one below it.
To graph #1 the vertex would be at -2 on the x axis and the y intercept would be 2
To graph #2 the vertex be at 2 on the x axis and the y intercept would be 2
Basically for #1 and #2 the plus and negative sign mean the opposite
If you need help graphing you can also go to the website Desmos

A sapling, or young tree, is planted in a garden. After 3 years, it is 180 cm tall. After 7 years, it is 368 cm tall. What is th

Mashcka [7]

The function modelled by the height (x) of the tree is as follows:
y - 180 = (368 - 180)/(7 - 3) (x - 3)
y - 180 = 47(x - 3) = 47x - 141
y = 47x - 141 + 180 = 47x + 39

Therefore, after 10 years, the tree will be 47(10) + 39 = 470 + 39 = 509 cm tall
