1 Given the functions: f(x) = 2x - 1 and g(x) = -3x - 9 1.1.1 Sketch f and g on the same system of axes. Label all intercepts with the axes.

1.1.2 Write down the domain and range of f.

1.1.3 Is the graph of g increasing or decreasing? Substantiate your answer

1.1.4 For which value(s) of x will f(x) > 0 (2) [10]​

question:

could we have options?

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
