The x-intercept would be (-4,0)
Answer:
Correct choice is B
Step-by-step explanation:
All three functions are increasing when x is increasing. You can find values of each function when x is "enough large". For example, at x=100,
1. linear function: 
2. exponential function: 
3. quadratic function: 
As you can see, when x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.
Also you can use graphical method to get from the attached diagrams result. When x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.
Correct choice is B.
Answer:
The measure of the arc DAC is 240°
Step-by-step explanation:
we know that
The semi-inscribed angle is half that of the arc it comprises.
so
m∠RDC=(1/2)[arc DAC]
we have
m∠RDC=120°
substitute
120°=(1/2)[arc DAC]
240°=[arc DAC]
Rewrite
arc DAC=240°
No; the 75% off sign implies that he is lowering the price, when he actually wants to increase the price.
