When will the dependent variable in the equation y squarero

When will the dependent variable in the equation y = squareroot x + 4 - 3 equal or exceed 4? x GE -0.17 x GE 45 x GE 48 x GE 53 Which function is shown on the graph below? y = squareroot 2x - 6 - 1 y = squareroot 2x + 6 + 1 y = squareroot 2x - 6 + 1 y = 2x + 6 - 1

Solution

7. y = sqrt(x+4) -3

y >=4

So, sqrt(x+4) -3 >=4

sqrt(x+4) >=7

x+4>= 49

x>= 45

Option b

8. Graph is shifted to left by 3 units

Graph is shifted vertically by 1 unit

So, possible equation : y = sqrt(x-6) +1
