Starting value 100 increases 5%

Brut [27]

Answer:

105

Explanation:

Adding 5% of 100, to 100 is:

100(0.05) + 100

What is the equation of the axis of symmetry do the quadratic function f(x) = -(x+4) (x-1)

miv72 [106K]

9514 1404 393

Answer:

x = -3/2

Step-by-step explanation:

The zeros of the function are the values of x that make the factors zero:

x = -4, x = 1

The axis of symmetry is the vertical line halfway between these zeros.

x = (-4 +1)/2 = -3/2

The equation of the axis of symmetry is x = -3/2.
