Write a quadratic function in the vertex form f(x) = a(x - h)^2 + k such that the graph of the function opens down and has a vertex at (10,- 9) and passes through point (7,-18)
The function is f(x)=

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
