Question

1.1) Use the graph of a function f to determine x or y to the nearest​ integer.

Answer 1

When f(x)=0 x=-1, 0, 8

Answer 2

F(x) = 0 is the same as saying y = 0. When y = 0, the line will cross the x-axis. Look for where the line crosses the x-axis.

The line crosses the x-axis at x = -1, x = 0, and x = 8. At these x-points, y will equal 0.

The answer is 'When f(x) = 0, x = -1, 0, -8.'
