Find the equation of a quadratic f(x) = 2(x+3)²-7 after being shifted 2 units up and 5 units right.

Three friends want to meet at a location that is the same distance from each other's house. Danny makes a grid to model each person's locations. 1 unit on the grid equals 3 miles. • Danny (5, 1) • Ethan (-2, 0) • Frank (4, 8) What is the approximate distance each person must travel?

The function f(x) = log(x) + 3, where x > 0, is moved 1 unit right and 4 units down, resulting in the function g(x). Which equation represents g(x)?

• g(x) = log(x + 1) - 4, where x > -1

• g(x) = log(x - 1) - 4, where x > 1

• g(x) = log(x + 1) - 1, where x > -1

• g(x) = log(x - 1) - 1, where x > 1

Which equation best matches the graph.
