Would it be y2 ? idk im not sure but i tried
Answer:
g(f(4)) = 9
Step-by-step explanation:
Fill in gf(x) for where x is in g(x): (x-7)²
Then, fill in 4 for where x is: (4-7)²
Square it: (-3)²
9

Answer:
y= 3x
Step-by-step explanation:
The slope is just read. It is 3. It is the value of m in the general equation.
y = mx + b
y = 3x + b
To find b, use (-1,-3)
x = -1
y = -3 Substitute into the general equation
-3 = 3(-1) + b Simplify the right side
-3 = -3 + b Subtract -3 from both sides
b = 0
Answer: y = 3x
Answer: The maximum height the football reaches = 51.89 feet.
Step-by-step explanation:
Given: The equation 
gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.
Differentiate the given equation, we get
(i)
Put 
Differentiate (i) w.r.t. t, we get
< 0 i.e. h is maximum at t= 1.65625
The value of h at t= 1.65625 will be 
Hence, the maximum height the football reaches = 51.89 feet.
