Answer 2

Answer:

-∞ to +∞

Step-by-step explanation:

let x be -0.499 then value of expression will be

(-0.499-2)/2(-0.499)+1 = -2.499/0.002= -1249.5

let x be -0.4999999 then value of expression will be

-2.4999999/0.0000002 = -12499999.5

so when value will reach -∞

Similarly for +∞. Let x be -0.5000001 then value of expression will be

(-0.5000001-2)/2(-0.5000001)+1 = -2.5000001/-000000.2= 12500000.5

it will reach to +∞ for values of x close to -0.5.

So when x->(-0.5) from left it reaches -∞

When x->(-0.5) from right it reaches +∞
