<h2>Answer:</h2>

1)

The domain is

          D.) All real numbers

2)

        The correct answer is:

          A.)    Left by 4 units

<h2>Step-by-step explanation:</h2>

Ques 1)

The equation of a parabola is:

          y=x^2-6x+1

The equation is a quadratic equation and we know that the polynomial function is defined for all of the x i.e. for all the real values.

Hence, the domain is:

              All real numbers.

Ques 2)

 Functions f(x) and g(x) are given by:

       f(x)=x^2

and g(x)=x^2+8x+16\\\\i.e.\\\\\\g(x)=(x+4)^2

i.e. the function g(x) could be written as:

          g(x)=f(x+4)

We know that the translation of the original function f(x) to f(x+k) is a shift of the function f(x) k units to the right or left depending whether k is negative or positive respectively.

Here k=4>0

Hence, the shift is 4 units to the left.

The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird
svlad2 [7]

Answer:

Average\ Change = -1\frac{7}{10} ft/s

Step-by-step explanation:

Given

Altitude\ Change = -4\frac{1}{4} \ ft

Time = 2\frac{1}{2}\ s

Required

Determine the average change

This is calculated as follows:

Average\ Change = \frac{Altitude\ Change}{Time}

This gives:

Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}

Average\ Change = -4\frac{1}{4}/2\frac{1}{2}

Convert to improper fractions

Average\ Change = -\frac{17}{4}/\frac{5}{2}

Convert to multiplication

Average\ Change = -\frac{17}{4}*\frac{2}{5}

Average\ Change = -\frac{17}{2}*\frac{1}{5}

Average\ Change = -\frac{17}{10}

Average\ Change = -1\frac{7}{10} ft/s
