Question:-
The equation of the function is y = 4x + 5. Find the value of y when
x = 3
x = -2
Answer:-
Given:-
y = 4x + 5 [Equation]
To Find:-
The value of y when x = 3 , x = -2
Solution:-
y = 4x + 5 [Given equation]
[tex] \therefore [/tex] When x = 3 ,
y = 4 × 3 + 5 [Value of x is 3]
y = 12 + 5
y = 17 [Answer]
Again, when x = -2 ,
y = 4 × (-2) + 5 [Value of x is -2]
y = -8 + 5
y = -3 [Answer]
