Respuesta :
The fourth function, f(x) = (x+2)^2-1 has an axis of symmetry of x = -2.
All of these functions start from the same function, f(x) = x^2, which has an axis of symmetry of x = 0.
What is a quadratic function?
A quadratic function is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The first function has been shifted 1 unit to the right and 2 units up, which have an axis of symmetry at x = 1.
The second function has been shifted 1 unit to the left and 2 units down, which have an axis of symmetry at x = -1.
The third function has been shifted 2 units to the right and 1 unit down, which have an axis of symmetry at x = 2.
The fourth function has been shifted 2 units to the left and 1 unit down, which have an axis of symmetry at x = -2.
As you can see, the last function has been shifted 2 units to the left, which has an axis of symmetry at x = -2.
Thus, The fourth function, f(x) = (x+2)^2-1 has an axis of symmetry of x = -2.
