Answer:
f(x)= - 4 (
) + 3
Step-by-step explanation:
1. start with f(x)=a(
+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(
+3
3. Then use the give point and substitute to find "a" value --> - 1 = a(
+3
--> - 1 = a + 3 --> a= - 4
4. put the "a" value into the #2. function/equation --> f(x)= - 4(
+3
January 18th $324.18
January 29th $487.38
$487.38 - $324.18 = $163.20
