jacob is riding his bike down the street in runville NY at a constant speed when a nail gets caught in one of his tires. The height of ther nail above ground in inces can be represented by the trigonometci fincvtion F(t)=-15cos(.6pi t)+15 where t represents the time in seconds since the nail first caight in the tire. A) determine the period of f(x). Interpret what the period means in the context B) does the height of the nail ever reach 3.5 inches above the ground?

step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
