We can transform this function by adding a constant to the original equation y=x^2. A new transformed function g(x) is given by g(x)=f(x)+c (where f(x)=y)
c>0 moves it up
c<0 moves it down
So: y=x^2+c
y=x^2-20
The new graph will be 20 units down the original.
Start by squaring both sides of the equation and it will make the problem a lot easier
Answer:
the correct answer is B. $336
Step-by-step explanation:
you first add 319 and 28. Then, you subtract the product with 11.
The distance between the focus and directrix is, in this case, 8. Since the directrix is at x= something, the parabola opens sideways, and since the directrix is on the left, to the right. In which case, y^2=p(x), where p is 4 times distance of half of distance between directrix and focus, so the answer is y^2=16x
40.96 is what I got. Hope this helps. :)
