Let's actually solve this problem:
<span>1/2x2 + 4x + 8 = 0 has coefficients a = 1/2, b = 4 and c = 8
Thus, the discriminant is b^2 - 4ac, or (4)^2 - 4(1/2)(8) = 16 - 16 = 0
When the discriminant is zero, as it is here, the quadratic equation has two real, equal roots (solutions).</span>
Answer:
A
Step-by-step explanation:
Given the roots are x = - 1, x = 0 and x = 4
Consider the graph where f(x) intersects with the x- axis at these points
The only graph is A
