The value of f(2) is -2 ⇒ 1st answer

Step-by-step explanation:

The form of the quadratic function is;

f(x) = ax² + bx + c, where

a is the coefficient of x²
b is the coefficient of x
c is the numerical term
x is the domain of the function and f(x) is the range of the function

∵ f(x) = -5x² - x + 20

- f(2) means value f(x) at x = 2

∵ x = 2

- Substitute x in the function by 2 to find f(2)

∵ f(2) = -5(2)² - (2) + 20

∴ f(2) = -5(4) - 2 + 20

∴ f(2) = -20 - 2 + 20

∴ f(2) = -2

The value of f(2) is -2

A tree of height y meters has, on average, upper b branches, where upper b equals y minus 3. Each branch has, on average, n leav

Mumz [18]

we are given

number of branches is

$B=y-3$

number of leaves on each branch

$n=2B^2-B$

the average number of leaves = (number of branches)*(number of leaves on each branch)

so, we can plug values

we get

$f(y)=B*n$

now, we can plug values

$f(y)=(y-3)*(2(y-3)^2-(y-3))$

now, we can simplify it

$f(y)=2y^3-19y^2+60y-63$ ............Answer
