Write the quadratic function for the parabola having vertex(4,2) and passing through the point (1,11)
Zigmanuir [339]
So the function we are looking for should look like f(x)=a(x-1)2-2, and since the parabola passes through (4,5), we have 5=a(4-1)2-2, which means 5=9a-2, so a = (7/9) and f(x) = (7/9)(x-1)2-2.

1/6 * n = 3<br><br> How do I solve this problem?
7nadin3 [17]
To solve this, you can rewrite it as n/6=3, as when you multiply a fraction and a whole number, you just multiply the whole number by the numerator. Next, as this is n divided by 6, to get the n by itself, you would multiply both sides by 6, giving you (6n)/6=3/6. Now, dividing this becomes n=3/6, with 3/6 being the same as 1/2, making n=1/2 be your answer.
