Answer:
a and c
Step-by-step explanation:
The equation of a quadratic in vertex form is
f(x) = a (x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 5)² + 7 ← is in vertex form
Thus the function is quadratic → a
• If a > 0 then the grapg will open upwards
• If a < 0 then the graph will open downwards
Here a = 1 > 0 then graph will open upwards → c
Answer: x=2

Answer:
Step-by-step explanation:
Alright, lets get started.
The given equation is :
If we divide the equation with -2 in both sides
Subtract 3 in both sides
So, the first step of simplifying equation is divide equation with -2. : Answer
