Given information:
The given function is \(f(x)=x^2\).
Concept Used:
If a is positve real number, then the graph of \(f(x-a)\) is the graph of \(y=f(x)\) shifted to the right a units.
If \(a>1\), the graph of \(y=cf(x)\) is the graph of \(y =f(x)\) stretched vertically by a.
If a is positve real number, then the graph of \(f(x)-a\) is the graph of \(y=f(x)\) shifted downward a units.
Calculation:
First, we have to shift the graph to the right by 7 units.
\(f(x-7)=(x-7)^2\)
Now, stretched the graph by a factor of 9 units.
\(9f(x-7)=9(x-7)^2\)
Now, shift the above graph downward by 3 units.
\(9f(x-7)-3=9(x-7)^2-3\)
Compare the new equation with the equation \(y=a(x-h)^2+k\), we get
\(h=7\) and \(k=-3\)
Final Statement:
The new coordinates of the vertex for the new parabola function is (7,-3)
The new function is
\(g(x)=9(x-70^2-3)\)

Starting with the function \(f(x) = e^x\), create a new function by performing the following transformations.
i. First shift the graph of f (x) to the left by two units.
\(f_1 (x) =\)?
ii. Then compress your result by a factor of \(1/7\)
\(f_2 (x) =\) ?
iii. Next, reflect it across the x-axis.
\(f_3 (x) =\) ?
iv. And finally shift it up by eight units to create g (x).
g (x) =?

For the cellar of a new house a hole is dug in the ground, withvertical sides going down 2.40m. A concrete foundation wallis built all the way across the 9.6m width of the excavation. This foundation wall is 0.183m away from the front of the cellarhole. During a rainstorm, drainage from the streetfills up the space in front of the concrete wall, but not thecellar behind the wall. The water does not soak into the clays oil. Find the force the water causes on the foundation wall. For comparison, the weight of the water is given by:
