A function is given.

f(x)=2x+3

What is the value of f(−2)?

f(−2) = ?

f(- 2) = - 1

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x), that is

f(- 2) = 2(- 2) + 3 = - 4 + 3 = - 1

For + 3, then

f(- 2) = + 3 = + 3 = 3.25

this answer is !

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
