Answer:

f(x) = (x-1)^2-6

Step-by-step explanation:

Rewrite the quadratic using the method of completing the square:

x^2-2x-5=(x^2-2x+1)-1-5=(x-1)^2-6\\f(x) = (x-1)^2-6

From this form it is immediately clear that the vertex of the parabola is at x=1 and its y-intercept at -6.

ziro4ka [17]

Ben drinks 1,050 liters of tea every 6 days.

<h3>How many liters of tea does Ben drink every 6 days?</h3>

Convert the object's dimensions into centimeters before performing the volume calculation in liters. Next, determine a shape's volume using the volume formula. The metric unit for measuring volume or capacity is the liter (or liter). Liters are a standard unit of measurement frequently used to measure liquids.

Divide Bens daily tea usage by the number daily tea usage rate.

Ben the camel drinks tea ( so classy ).

He drinks 350 liters of tea every 2 days.

liters (Volume) = usage times /days

350 × (6/2)

= 350 × 3

= 1,050 liters of tea does Ben drink every 6 days.

As a result, Ben drinks 1,050 liters of tea every 6 days.

just subsitute -3 for x

(-3)³=(-3)(-3)(-3)=-27
answer is -27
