Outside temperature over a day can be modelled as a sinusoidal function. Suppose you know the high temperature for the day is 85 degrees and the low temperature of 45 degrees occurs at 5 AM. Assuming it is the number of hours since midnight, find an equation for the temperature, D, in terms of t.

answer: add the !

step-by-step explanation: then we will answer

pls refer ro the top for answer

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
