The function f(x) is graphed on the coordinate plane. what is f(−1) ? enter your answer in the box. f(−1)f(−1) = graph of a line on a coordinate plane. the horizontal x axis ranges from negative 5 to 5 in increments of 1. the vertical y axis ranges from negative 5 to 5 in increments of 1. a line passes through the points begin ordered pair 2 comma negative 3 end ordered pair and begin ordered pair negative 1 comma 3 end ordered pair.

f(-1)=3

Step-by-step explanation:

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

It is given that a line passes through the points (2,-3) and (-1,3).

We need to find the value of f(-1). It means we need to find the value of function at x=-1.

If the graph of a function f(x) passes through a point (a,b) where a and b are real numbers, then the value of function at x=a is b.

The graph of function f(x) passes through the point (-1,3), so

Therefore the value of f(-1) is 3.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
