Riza is 13 years old now. Her mother will be 3 times as old as her in 3 years time. What was their age 3 years ago?

riza =10 years old

her mom =45years

Riza's age after 3 years

= 13+3

=16 years

so her mother's age

=16×3

=48 years

so Riza and her mother's age before 3 years will be

13–3

=10 years Riza's age

48-(3+3)

48-6

=42 years

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

the diver is 33 feet below the surface.
