the forecast predicts that the temperature will change from 15° fahrenheit to -3° fahrenheit on saturday
a. write an expression that represents the change in temperatures for saturday.
b. what is the expected temperature change?
c. if the temperature actually changes by 5° fahrenheit more than predicted, what will be the change in
temperature?

it would be 3 ÷by 6 because the number on each side

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
