top left

Step-by-step explanation:

Consider finding points on the graph using the equation.

x = 0 : f(0) = + 4 = 1 + 4 = 5 ← y- intercept

Since y- intercept is 5, this excludes the lower 2 graphs, which have y- intercepts of 1

x = 1 : f(1) = + 4 = 0.5 + 4 = 4.5 ⇒ (1, 4.5 )

x = - 1 : f(- 1) = + 4 = + 4 = 2 + 4 = 6 ⇒ (1, 6 )

These points lie on the top left graph

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
