a) Increasing b) $f(1) = -4$ c) $x = -2$ d) $y = -8$

Work Step by Step

a) Increasing because you can see it starts from the bottom left and increases to the top right. b) $f(1) = -4$ at point $(1, -4)$ by referring to the graph. c) $x = -2$ at point $(-2, -32)$ by referring to the graph. d) $y = -8$ at point $(0, -8)$, look at the $y$ intercept on the graph.
