Question

The equation of the function is Y=4x+5.Find the value of y when x=3 x=-2

Answer 1

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]

$\therefore$ 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]
