F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.
Answer:
x < 16 ft
Step-by-step explanation:
Perimeter = x
If it is less than 16, the equation is:
x < 16

Answer:
h(x)=1/4x
Step-by-step explanation:
Inverse function is when the domain and range of a function are swapped, or in other words the y and x values are swapped.
To do this you simply change x to y, and y to x in the equation
So we have the original equation
y = 4x
swap y and x
x = 4y
now solve for y by dividing by 4
y = x/4
which can also be expressed as h(x)=1/4x

Answer:
(x-5)^2+2
Step-by-step explanation:
To convert between standard and vertex form, you have to complete the square (which, as a reminder, (a+b)^2 = a^2+2ab+b^2).
Since a^2 is x^2, and 2ab is -10x, then b must be -5, so b^2 is 25. Therefore, we add and subtract 25 from the expression:
(x-10x+25)+27-25
Then, we can make (x-10x+25) to (x-5)^2:
(x-5)^2+2
