Step-by-step explanation:
f(2) = a means find the value of y corresponding to x = 2
Locate x = 2 on the x- axis, go vertically down to meet the line and read off the corresponding value of y from the y- axis, that is y = - 3
Hence f(2) = - 3 ⇒ a = - 3
f(b) = 0 means what is the value of x for y = 0
The line crosses the x- axis at x = - 4, where the y- coordinate is zero, thus
f(b) = 0 ⇒ b = - 4
f(- 2) = c means what is the value of y when x = - 2
Locate x = - 2 on the x- axis, go vertically down to meet the line and read off the corresponding value of y from the y- axis, that is y = - 1
Hence f(- 2) = - 1 ⇒ c = - 1
f(d) = - 6 means what is the the value of x when y = - 6
Locate y = - 6 on the y- axis, go horizontally across to meet the line and read off the corresponding x- coordinate, that is x = 8
Hence f(8) = - 6 ⇒ d = 8
