Answer:

x=-1

x=-2

Step-by-step explanation:

1. To solve this problem you can graph the quadratic function, as you can see in the graph attached.

2. You can estimate the solution of the quadratic function by observing two points where the parabola intersect the x-axis.

3. Keeping the the information above on mind, you can estimate that the solution is:

x=-1

x=-2

NOTE:

You can also find two numbers whose sum is 3 and whose product is 2. Then:

(x+2)(x+1)=0\\x=-2\\x=-1

Find the domain and range of 1/t+2
kotegsom [21]

Answer:

Domain = (-∞, -2) ∪ (-2, ∞).

Range =  (-∞, 0) ∪ (0, ∞).

Step-by-step explanation:

t can't have the value -2 because that would make  1/(t + 2) = 1/0 which is undefined.

So the domain is All real values of t. except t = -2.

As t approaches infinity or negative infinity  f(t) approaches  zero, and as t approaches -2 from below or above f(t) approaches negative infinity or positive infinity.
