Answer:
The correct option is 1.
Step-by-step explanation:
The given parent function is
1. Domain of the function is all positive real number including 0.
2. Range of the function is all positive real number including 0.
3. It is an increasing function. It increases at decreasing rate.
First graph increase at decreasing rate and it starts from (-4,-1), therefore the required function is
Therefore graph 1 is an example of a function whose parent graph is of the form y = √x.
Second graph is a parabola, so it is the graph of a quadratic function.
Third graph is a rectangular hyperbola, so it is the graph of a rational functions.
Fourth graph is increasing at increasing rate, so it is the graph of an exponential function.
Therefore options 2, 3 and 4 are incorrect.
The equation for his currnet sales can be as follows:
x=520*2^n
n is the current month
We are looking for the sum of next 3 months, so n+1, n+2 and n+3.
520*2^(n+1)+520*2^(n+2)+520*2^(n+3)=520*4+520*8+520*16=2080+4160+8320=14560
Ok,
divide by 2 on both sides...
So X = 3/8!
Answer:
the first one (3x-2)(2x-3)
Vertical line are represented by x = a number....that number being the x value in ur set of points
so ur equation is : x = -7
