Question

given the graph of y=f(x) below, solve for f(x)=3. enter multiple values as a list separated by commas.

Answer 1

To find where f(x) = 3 on the graph of the equation y = 9 + 3x, we solve the equation 9 + 3x = 3 to find that x = -2.

Step-by-step explanation:

To solve for f(x) = 3 given the graph of y=f(x), we look for the point(s) where the graph of the equation crosses the line y=3. Since the equation given is y = 9 + 3x, we would set this equal to 3 to find the corresponding x-value(s). The process is as follows:

y = 3

9 + 3x = 3 (Substitute y with 3)

3x = 3 - 9 (Subtract 9 from both sides)

3x = -6 (Result of subtraction)

x = -6 / 3 (Divide both sides by 3)

x = -2 (Simplified)

Thus, the solution to f(x) = 3 is x = -2.
