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
The answer is x = {-1, 9}
Hope this helped Mark me as brainliest pls
Answer: g(x) decreases by 7
Step-by-step explanation:
Simple algebra and substitution of variables for the number can help you to solve the problem,
g(7)=50-2(7)
g(7)=50-14
g(7)=36
I hope this helps
I am also not sure, because I also asked this question.
