Let f(x)=2x^2−1.
the quadratic function g(x) is f(x) translated left 2 units.
enter the equation of g(x)
answer- 2(x+2)^2-1

If we begin with   f(x)=2x^2−1 and graph this quadratic, and then translate the entire graph 2 units to the left, we get g(x) = 2(x+2)^2 -1.

Were it 4 units to the left, then h(x) = 2(x+4)^2 - 1 (example only)

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units
