Use the given two points to find a and b
when x=1, y=7.5, so a*b=7.5
when x=3, y=16.875, so a*b³=16.875
divide ab³ by ab to eliminate a: b²=16.875/7.5=2.25, b=1.5
a=7.5/1.5=5

The vertex of this parabola is at (-4,-1).When the y-value is 0,the x-value is 2.What is the coefficient of the squared term in
densk [106]

Answer:

  1/36

Step-by-step explanation:

When the coefficient is 1, the function has zeros at -3 and -5, one horizontal unit from the vertex. You want to move the zero to (2, 0), which is 6 units from the vertex. To achieve a horizontal stretch by a factor of 6, the value of x in the function must be replaced by x/6. That would make the coefficient of x^2 be (1/6)^2 = 1/36.

The coefficient of the squared term is 1/36.
