Answer:
option A
(1.5,1.2)
Step-by-step explanation:
Given in the question two equations
Equation 1
y = √x
Equation 2
y = x²- 1
Equate both equations
√x = x²- 1
<h3>1 method </h3><h3>by plotting graph</h3>We can see from the graph that both meets when x = 1.5 and y = 1.2
<h3>2 method </h3>we can plug the options given one by one to see which points satisfy
one thing we know is that x ≠ any negative value since
y = √x and square root of negative value is not possible
so option b and c are rejected
option A
√1.5 = y = 1.2
1.5²- 1 = y = 1.2
Answer:
See picture below
Step-by-step explanation:
To graph properly, remember that:
- The y intercept of the function, is the value of the function when x=0, and tells (in this case y=1 is the intercept). Locate this point in the graph.
- The x intercept, which is the value of x when y=0 is x=1. Locate it in the graph.
- You now have two points of a straight line: join this two points and you would have done it!
