For each equation, what input value will produce the smallest possible output? (In other words, what is theAre there any-values that yield a negative number? It is impossible forto be negative in this case. In turn, what is the lowest value can be? Can equal ?is equal to , is equal to , which is the smallest possible output. Does this parabola open upward or downward? It opens upward. Therefore, there will be a smallest output. See part (a). See part (b). Notice the negative sign in front of theterm. How does that change the parabola?
