1. The problem asks us to compare the intercepts of two functions: \(a(x) = -x^3 + 8\) and function \(b\) represented by the given graph. 2. First, find the intercepts of function \(a(x)\): - The y-intercept occurs when \(x=0\): $$a(0) = -0^3 + 8 = 8$$ So, the y-intercept of \(a\) is \((0, 8)\). - The x-intercept(s) occur when \(a(x) = 0\): $$-x^3 + 8 = 0 \implies -x^3 = -8 \implies x^3 = 8 \implies x = 2$$ So, the x-intercept of \(a\) is \((2, 0)\). 3. From the graph description of function \(b\): - The y-intercept is at \((0, 8)\). - The x-intercept is near \((-2, 0)\). 4. Compare the intercepts: - Y-intercepts: \(a\) and \(b\) both have y-intercept \(8\), so they are equal. - X-intercepts: \(a\) has x-intercept at \(2\), \(b\) has x-intercept near \(-2\). Since \(2 > -2\), the x-intercept of \(b\) is less than that of \(a\). 5. Therefore, the correct statement is: **C. The y-intercept of b is equal to the y-intercept of a.**
