1. <span>y = (x - 8)² + 15 </span>
2. The standard form is <span>Ax² + By = C. Using a
complete sentence the FOIL strategy on (x - 8)²</span>, I’d combine it
with 15.
<span>3A. y = 4(x - 8)² + 15 </span>
3B. <span>y =
-0.1(x - 8)² + 15.</span>
The value of “a” is similar to a slope. The bigger a is, the
smaller the slope. Moreover, if a is negated then it will flip the graph.
5. The average change rate is equal to <span>[f(7) - f(4)] / (7 - 4) and this means it’s simply the slope
of the line among two points. </span>
6. <span>y = (x
- 6)² + 20. This will move 2 units to the
left and move up 5 units.</span>
I am hoping that these answers have somewhat satisfied your
query about these specific questions.
