Use the graph of a function (f) to determine (x) or (y) to the nearest integer, as indicated. Some problems may have more than one answer.

(30=f(x))

When (f(x)=30), (x=)

Transcript text: Use the graph of a function $f$ to determine $x$ or $y$ to the nearest integer, as indicated. Some problems may have more than one answer. \[ 30=f(x) \] When $f(x)=30, x=$ $\square$

Solution

Solution Steps

Step 1: Understand the Problem

We need to find the value of $ x $ when $ f(x) = 30 $ using the given graph of the function $ f $.

Step 2: Locate $ y = 30 $ on the Graph

Identify the horizontal line on the graph where $ y = 30 $.

Step 3: Find the Intersection Points

Determine the points where the horizontal line $ y = 30 $ intersects the graph of the function $ f $.

Step 4: Read the Corresponding $ x $-Values

From the intersection points, read the corresponding $ x $-values on the x-axis.

Final Answer

The value of $ x $ when $ f(x) = 30 $ is approximately $ x = -2 $ and $ x = 2 $.
