The function f(x) is graphed on the coordinate plane. what is f(−2) ? enter your answer in the box. f(−2)=

The value of f(-2) is, -2

Step-by-step explanation:

The graph which is shown on the coordinate plane passes through the two points i.e, (2,0) and (0, -1).

First find the equation for this line:

Using Point-Slope form for the equation of line:  ..[1]

where m is the slope given by ;

First find the slope:

⇒

Now, substitute the value of m= , = 2and =0 in equation [1];

or

In this graph x represents the input of the process and Y the output of the process and f the function of the variable x i.e, y=f(x)

∴        ....[2]

now, we put the value of x=-2 inequation [2] to solve for f(-2).

Simplify we get;

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
