In Fig. 7.2, a find the value of y when x = -2-5,

Answer:
Given equation: y = x² + 2x - 3
If you wish to find the values of y when x = -2 and x = -5:
When x = -2:
⇒ y = (-2)² + 2(-2) - 3
⇒ y = 4 - 4 - 3
⇒ y = -3
When x = -5:
⇒ y = (-5)² + 2(-5) - 3
⇒ y = 25 - 10 - 3
⇒ y = 12
If you wish to find the value of y when x = -2-5:
When x = -2-5 ⇒ x = -7
⇒ y = (-7)² + 2(-7) - 3
⇒ y = 49 - 14 - 3
⇒ y = 32
Answer:
y = 32
Step-by-step explanation:
Given :-
y = x² + 2x - 3
x = -2-5 = -7
To Find :-
y
Inputting the value of x :
y = (-7)² + 2(-7) - 3
y = 49 - 17
Solution :-
y = 32
