Answer asap!

the function f(x) is graphed on the coordinate plane.

what is f(−1) ?

enter your answer in the box.

f(−1)
=

f(-1) = 3

Step-by-step explanation:

See the graph shown in the attached file with the given question.

The graph passes through (0.5,0) point on the X-axis and (0,1) point on the Y-axis.

So, the length of the X-intercept is 0.5 and that of Y-intercept is 1.

Hence, the equation of the straight line graph is  

{Using the intercept form}

⇒ 2x + y = 1 ....... (1)  

Now, y = f(x) = 1 - 2x

Hence, f(-1) = 1 - 2 ( - 1 ) = 3 (Answer)
