For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following diagram shows the main properties: If k > 0, the vertex is a minimum turning point If k < 0, the vertex is a maximum ...

The donor bacterium carries a DNA sequence called the fertility factor, or F-factor. The F-factor allows the donor to produce a thin, tubelike structure called a pilus, which the donor uses to ...

To get the number inside the bracket, we half the coefficient of the second term in the original equation ... Next we need to take a common factor of \(- 1\) outside the brackets so that the ...
