Question

Write f(x) = 5(x - 2)2 - 7 in standard form.​

Answer 1

Answer: f(x)=5x2−20x+13

Explanation:

Answer 2

To write f(x) = 5(x - 2)2 - 7 in standard form, we need to expand the squared term first:

f(x) = 5(x - 2)(x - 2) - 7

f(x) = 5(x2 - 4x + 4) - 7

f(x) = 5x2 - 20x + 13

Therefore, the standard form of f(x) = 5(x - 2)2 - 7 is f(x) = 5x2 - 20x + 13.
