To rewrite the quadratic function in standard form, start by expanding the expression. The given function is \( y = 2(x + 5)^2 - 4 \). First, expand \( (x + 5)^2 \): \[ (x + 5)^2 = x^2 + 10x + 25. \] Now multiply it by 2: \[ 2(x^2 + 10x + 25) = 2x^2 + 20x + 50. \] Finally, subtract 4: \[ y = 2x^2 + 20x + 50 - 4 = 2x^2 + 20x + 46. \] So, the function in standard form is: \[ y = 2x^2 + 20x + 46. \]
