Answer:
3rd option
Step-by-step explanation:
x < 7
means that x cannot equal 7 but all values less than 7
since not equal at either end of interval use parenthesis, not brackets , then
(- ∞ , 7 ) ← is the required interval
Answer:
3.4 x 107
Step-by-step explanation:
The correct answer is choice C. Here is the reason. If you substitute the information into the formula this is what it would be:
A = bh/2
13 = x (6x + 1)/2
13 = (6x^2 + x)/2
26 = 6x^2 + x
0 = 6x^2 + x - 26
Answer:
Option C g(x) = -4
Step-by-step explanation:
In the question a function f(x) =4 is given and we are required to tell the reflection g(x) of the given function.
The rule of reflection for a function says that:
f(x) -> - f(x)
So, in our case the value of function is f(x) = 4, after reflection the value across the x-axis the value will become negative i.e -4,
so the required function g(x) = - 4
Hence Option C g(x) = -4 is correct option.
