Question 478849
i believe that function would be f(x) = x^2 - 7
here's a graph that shows both f(x) = x^2 and f(x) = x^2 - 7
{{{graph(400,400,-5,5,-10,10,x^2,x^2-7)}}}
for every value of x, the equation of f(x) = x^2-7 will be 7 units below f(x) = x^2.
here's a table with a couple of value of x to show you:
<pre>
    x        x^2        x^2-7
    -2        4          -3
    -1        1          -6
    1         1          -6
    2         4          -3
