The function f(x) is graphed on the coordinate plane. What is f(-1)?

find the equation of the line using y = mx + b. Then translate it as a function.

f(x) = -2x + 1

f(-1) = -2(-1) + 1

f(-1) = 3

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
