1. y = (x - 8)² + 15
2. The standard form is Ax² + By = C. Using a complete sentence the FOIL strategy on (x - 8)², I’d combine it with 15.
3A. y = 4(x - 8)² + 15
3B. y = -0.1(x - 8)² + 15.
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 [f(7) - f(4)] / (7 - 4) and this means it’s simply the slope of the line among two points.
6. y = (x - 6)² + 20. This will move 2 units to the left and move up 5 units.
I am hoping that these answers have somewhat satisfied your query about these specific questions.
My birthday is July 11. hence h is equal to 7 and k is equal to 11. The equation thus is (x-7)^2 = 2*4(y-11). The equation is expanded intp x^2 - 14x +49 = 8y - 88 or equivalent to x^2 - 14 x + 137 - 8y = 0. A wider latus rectum would mean a should be greater than 2, let's say 4. Hence the h(x) is equal to (x-7)^2 = 4*4(y-11) =16 y - 176. The expanded form is x^2 - 14 x + 49 = 16 y -176. This is equal to x^2 - 14 x + 225 - 16y = 0. A narrower graph means a less than 2, let's say 1. This is equal to (x-7)^2 = 1*4(y-11) or g(x) = x^2 - 14 x + 93 - 4y = 0
