Question

The black graph is the graph of

y = f(x). Choose the equation for the
red graph.
a. y = f(x - 1)
b. y = f(²)
c.
d.
y - 1 = f(x)
²/₁ = f(x)

Answer 1

c

Explanation:

given f(x) then f(x) + c is a vertical translation of f(x)

• if c > 0 then a shift up of c units

• if c < 0 then a shift down of c units

here the red graph is i unit above the black graph , then c = + 1

and equation is

y = f(x) + 1 ( subtract 1 from both sides )

y - 1 = f(x)
