damaskus [11]3 years ago
5 0

Answer:

f(x)= - 4 (x^{2}) + 3

Step-by-step explanation:

1. start with f(x)=a(x-p)^{2}+q

2. in that vertex is (p,q) noticing that use given vertex(0,3) and change the equation/function --> f(x)=a(x-0)+3 --> f(x)=a(x)^{2}+3

3. Then use the give point and substitute to find "a" value --> - 1 = a(1)^{2}+3

--> - 1 = a + 3 --> a= - 4

4. put the "a" value into the #2. function/equation --> f(x)= - 4(x)^{2}+3
