Graph the line that passes through the points (9, -9) and (9,−4) and determine the equation of the line.

x = 9

Step-by-step explanation:

Since both points share the same x-coordinate, look no further.

It has to be a vertical line with x-coordinate 9.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
