To find the x-intercept of the function \( f(x) = 3x - 7.5 \), you need to set \( f(x) \) equal to zero and solve for \( x \).
So, you start by setting the equation to zero:
\[
3x - 7.5 = 0
\]
Next, add \( 7.5 \) to both sides:
\[
3x = 7.5
\]
Now, divide both sides by \( 3 \):
\[
x = \frac{7.5}{3} = 2.5
\]
Therefore, the x-intercept of the function \( f(x) = 3x - 7.5 \) is at \( x = 2.5 \).
