Question

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.

Answer 1

Answer:

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.

$f(a)=b$

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

$f(-1)=3$

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