What is the equation of the parabola that has a vertex at # (77, 7) # and passes through point # (82,32) #?

Answer 1

#y=(x-77)^2+7#

The vertex form of a parabola is #y=a(x-h)^2+k#, where the vertex is #(h,k)#.
Since the vertex is at #(77,7)#, #h=77# and #k=7#. We can rewrite the equation as:
#y=a(x-77)^2+7#
However, we still need to find #a#. To do this, substitute the given point #(82, 32)# in for the #x#- and #y#-values.
#32=a(82-77)^2+7#
Now, solve for #a#.
#32=a(82-77)^2+7# #32=a(5)^2+7# #32=25a+7# #25=25a# #a=1#
The final equation is #y=1(x-77)^2+7#, or #y=(x-77)^2+7#.

Answer 2

The equation of the parabola with a vertex at (77, 7) and passing through point (82, 32) is:

y = a(x - h)^2 + k

Where (h, k) is the vertex.

Substitute the vertex coordinates:

y = a(x - 77)^2 + 7

To find the value of 'a', use the point (82, 32):

32 = a(82 - 77)^2 + 7

Solve for 'a':

32 = a(5)^2 + 7 32 = 25a + 7 25a = 32 - 7 25a = 25 a = 1

So, the equation of the parabola is:

y = (x - 77)^2 + 7

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
