Which statements about the graph of the function f(x) = -x2 - 4x + 2 are true? Select three The domain is {x|x S-2}.
The range is {yly s 6).
The function is increasing over the interval (-0, -2).
The function is decreasing over the interval (-4,00).
The function has a positive y-intercept.

the correct answer is 828.07

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
