Answer 1

To find the x-intercepts of the function \( g(x) = (4x - 1)(x + 2) \), you need to set the function equal to zero and solve for \( x \):

\[ (4x - 1)(x + 2) = 0 \]

This equation will be satisfied when either of the factors is equal to zero.

1. Set the first factor to zero: \[ 4x - 1 = 0 \] \[ 4x = 1 \implies x = \frac{1}{4} = 0.25 \]

2. Set the second factor to zero: \[ x + 2 = 0 \] \[ x = -2 \]

Therefore, the x-intercepts are \( (0.25, 0) \) and \( (-2, 0) \).

The correct response is: (0.25, 0) and (-2, 0)
