Chapter 2: Q. 4 (page 76)

If the point 5,-3 is a point on the graph of f, thenlocalid="1647336108610" f5=________.

Short Answer

Expert verified

The value off5=-3

Step by step solution

01

Step 1. Definition

For a function, no input has more than one output. The domain of a function is the set of all inputs; the range is the set of all outputs.

02

Step 2. Final answer

The input value is x-coordinate and the output value is y-coordinate in 5,-3.

So, fx=y.

Substitute value of x=5and y=-3in f(x)=y,

f5=-3
