Tyrone is twice as old as his daughter. In six years Tyrone's age will be
three times what his daughter's age was six years ago. How old are
they at present? write 2 equations.

x + y = 7

x^2 + y^2 = 25

Step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
