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
Hello!
The sum of all angle measures in a heptagon in 900°. We will subtract all of these angles from 900 to find our answer.
900-146-122-142-140-110-142=98
x=98°
I hope this helps!
we are given in the problem the number of hours Peter has played for video games. In this case, f(x) is the number of hours of playing with x as the number of weeks of playing. In this case, the equation f(x) = 5x.
I did this last semester and I would remember it but unfortunately this was the only section I didn't study for the final bc we did one day on it. I'm sorry. Good luck.
