The function f(t) = 4t2 - 8t + 6 shows the height from the ground f(t), in meters, of a roller coaster car at different times t. write f(t) in the vertex form a(x - h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t).

a. f(t) = 4(t - 1)2 + 3; the minimum height of the roller coaster is 3 meters from the ground

b. f(t) = 4(t - 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground

c. f(t) = 4(t - 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground

d. f(t) = 4(t - 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground

F(t) = 
The formula to use is: a(x-xv)^2+yv
where a is the coeficient of x^2, xv= -b/2a (b is the coeficient of x) and yv= -delta/4a or f(xv)

xv = 8/8 =1
yv = f(xv)=f(1) = 2

f(t) = 4(t-1)^2+2 the minimum value is 2 when t=1

The answer to your question is C. I hope this is the answer that you are looking for and it comes to your help.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
