The discriminant of a function is the b² - 4ac in the quadratic formula.

If it is positive, there are two real solutions.  The parabola only has one real solution on the graph (its vertex), so it can't be positive.

If the discriminant is negative, there are no real solutions.  In the quadratic formula, you have to take the square root of the discriminant, and you can't take the square root of a negative number to result in real solutions.  This doesn't apply to this graph either.

If the discriminant is zero, there is one real solution.  You can see the function touching the x-axis in one place, so your answer should be A.

Answer:

  b⁶

Step-by-step explanation:

The question tells you how to work it: use the relations you studied.

Here, you have the power of an expression with an exponent. The exponents multiply.

  \text{Rule: }(a^b)^c=a^{bc}\\\\\text{Appication: }(b^3)^2=b^{3\cdot2}=\boxed{b^6}

_____

<em>Additional comment</em>

A coefficient is used to indicate repeated addition: 3x = x + x + x.

An exponent is used to indicate repeated multiplication: x³ = x·x·x.

This is still true when the exponent is applied to an expression with an exponent:

  (b³)² = (b³)(b³) . . . . the factor b³ is repeated 2 times as indicated by the exponent 2

Of course, each of these indicates repeated multiplication, so we really have ...

  (b³)(b³) = (b·b·b)·(b·b·b) = b·b·b·b·b·b

And this can be simplified using an exponent to show the repeated multiplication:

  = b⁶

Then, by going the long way around, we arrive at ...

  (b³)² = b⁶
