Answer:
c
Step-by-step explanation:
Domain of a Function is a Set of Values under which the Function is defined or a Set of Values which satisfy the respective Function.
The Given Function is : f(x) =
The Condition for Square Root to be defined is any Expression under it should be Greater than or Equal to Zero.
When Function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)
According to Above Conditions Described above, The Given Function is Definable only when the Expression which is under the Square Root is Greater than Zero.
⇒ 2x + 10 > 0
⇒ 2x > -10
⇒ x > -5
In Set Builder Form it is Expressed as { x | x > -5 }
Answer:
True
Step-by-step explanation:
This is true for a>0 and x>0. We can prove it by plugging in a and x for f(x) = ln(x)
f(ax) = ln(ax) = ln(a) + ln(x)
We see that ln(a) + ln(x) is exactly f(a) + f(x)
Therefore, the statement above is true for any a>0 and x>0
The correct answer would be (0,2) since in standard form the y-int is C/B
C=-4 & B=-2
C/B = -4/-2 4/2 = 2/1 = 2
y-intercept = 2
Answer:
(x + 4) (x + 1)
