Answer» Given : 4 Functions f(x) and has axis of symmetry of x = - 2 To find : Which function has axis of symmetry of x = - 2 f(x) = (x − 1)² + 2 f(x) = (x 1)² − 2 f(x) = (x − 2)² − 1 f(x) = (x + 2)² − 1 f(x)=a(x-H)²+k will have symmetry an axis of symmetry of x = h putting h = -2 => f(x) = a(x-(-2) )²+k => f(x) = a(x + 2)² + k Comparing with given Equations f(x) = (x + 2)² − 1 MEETS it hence function f(x) = (x + 2)² − 1 has an axis of symmetry of x = −2 Learn more: The axis of symmetry for the graph of the function f start bracket x ... the ANGLE made by the line passing through(1,0)and(2,3)with x-axis is |
