Z/4-8z+2(z-5)=12/4-8(12)+2(12-5)=3-96+2(7)=3-96+14=-79
A. -79
Step-by-step explanation:
(a - b)²
= a² - 2ab + b²
= (a² + b²) - 2(ab)
= (33) - 2(7)
= 19.
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.
