2 over 3 divide by -1 1 over 3

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

m∠a is 90°

m∠b is 40°
