Two quadratic functions are represented below. f(x)=-x^2+4x-3
(the other is the graph)
A. In two or more complete sentences, explain how you can determine the maximum value of the quadratic functions, f(x) and g(x).
B. Which function has the greater maximum value, f(x) or g(x)?

please help me i dont understand this at all and i need to. thank you so much if you answer ill give brainliest too

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
