Murrr4er [49]3 years ago

Step-by-step explanation:

we solve for x

15x-(2/x)>1. /*x

15x^2 -2 > x. /-x

15x^2 -x -2 > 0

Solve the quadratic at zero

15x^2 -x -2=0

using the quadratic formula

x1,2 = [1+-sprt((-1)^2-4(15)(-2))]/2(15)

= [1+- sqrt (121)]/30

= [1+-11]/30

x1= 12/30= 2/5

x2= -10/30= -1/3

therefore this positive parabola is greater than zero or positive when

x< -1/3 and x> 2/5

x< -1 is the graph going down or up when x is less than -1?  its going down , so this is true

Range is the y values.  It appears to go down to y=5 and go up so its not all reals

x< -1 is the graph going down or up when x is less than -1?  its going down , so this isn't true

Domain is the x values and it does include all reals

Minimum (-1, 5), is that the value of vertex at the bottom, yes it is, so this is true
