1. Problem Description

The problem asks us to find the x-intercepts of the quadratic function h(x)=3x27x+2h(x) = 3x^2 - 7x + 2. We need to choose two correct x-intercepts from the list of options.

2. Solution Steps

First, we need to factor the quadratic expression 3x27x+23x^2 - 7x + 2. We are looking for two numbers that multiply to (3)(2)=6(3)(2) = 6 and add up to 7-7. These numbers are 6-6 and 1-1.
We can rewrite the middle term as 7x=6xx-7x = -6x - x, so we have:
3x27x+2=3x26xx+23x^2 - 7x + 2 = 3x^2 - 6x - x + 2
Now we factor by grouping:
3x26xx+2=3x(x2)1(x2)=(3x1)(x2)3x^2 - 6x - x + 2 = 3x(x - 2) - 1(x - 2) = (3x - 1)(x - 2)
Thus, h(x)=(3x1)(x2)h(x) = (3x - 1)(x - 2).
To find the x-intercepts, we set h(x)=0h(x) = 0 and solve for xx:
(3x1)(x2)=0(3x - 1)(x - 2) = 0
This gives us two solutions:
3x1=03x=1x=133x - 1 = 0 \Rightarrow 3x = 1 \Rightarrow x = \frac{1}{3}
x2=0x=2x - 2 = 0 \Rightarrow x = 2
The x-intercepts are the points where the graph crosses the x-axis, i.e. when y=h(x)=0y = h(x) = 0. The x-intercepts are (13,0)(\frac{1}{3}, 0) and (2,0)(2, 0).

3. Final Answer

The x-intercepts are (13,0)(\frac{1}{3}, 0) and (2,0)(2, 0).
