Finding an output of a function from its graph

f(-2) = 0.

Step-by-step explanation:

WE see that the graph cuts the x-axis  when x = -2 and the values of f(x) at this point is 0.

Step-by-step explanation:

Draw a real or imaginary vertical line through the input (x-) value.  The corresponding output (y-) value can be read from the graph.  

For example:   If x = -2, we see that the vertical line x = -2 intersects the graph at y = 0, which is the output of this function when the input is =2.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
