Answer:
(-1,-18) is the coordinate of the vertex.
Step-by-step explanation:
We can obtain the vertex by taking the derivative and equating it to zero. I know this because the the slope of the tangent line at the vertex has to be equal to zero.
the derivative would be 4x + 4 = 0, where x = -1.
Plugging x into the original value we will end up with the y coordinate.
Hope this helps.
Answer:
<h3>
f(x) = -2
(x - 3)² + 6</h3>
Step-by-step explanation:
The vertex form of the equation of the parabola with vertex (h, k) is:
f(x) = a(x - h)² + k
so the equation of parabola with the vertex (3, 6) is
f(x) = a(x - 3)² + 6
passes through the point (4, 4) means: if x=4 then f(x)=4
4 = a(4 - 3)² + 6
4 -6 = a(1)² + 6 -6
-2 = a
Therefore the equation of parabla is:
<u> f(x) = -2
(x - 3)² + 6 </u>
0.68.....the last digit (8) is in the hundredths place...so put the 68 over 100 and reduce.
68/100 = 17/25
