Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 > 0?

We have to determine the graph of the given inequality as:

on solving this equation we get:

Since we know that:

Now we know that when the value of:

Also for the value other than -1 the function being a quadratic function will always give a non-zero positive value.

Hence, range of the function in intervals could be written as:

(-∞,-1)∪(-1,∞).

Hence, the graph of the function will be the whole of the number line with a open circle on -1.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
