Answer:

option A

(1.5,1.2)

Explanation:

Given in the question two equations

Equation 1

y = √x

Equation 2

y = x²- 1

Equate both equations

√x = x²- 1

1 method

by plotting graph

We can see from the graph that both meets when x = 1.5 and y = 1.2

2 method

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
