Answer:
Its the first choice.
Step-by-step explanation:
x^2+4x-4 = 8
x^2 + 4x - 4 - 8 = 0
x^2 + 4x - 12 = 0
(x + 6)(x - 2) = 0
x = -6, 2.
Answer: $15
Step-by-step explanation:
$780 - $180 = $600
$600/40hrs = $15
We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.
For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.
We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.
