Answer:
f(x) = 10x - 2x + 4.
Step-by-step explanation:
This is linear because the degree of x is 1.
The others have degree 2 , degree 3 and degree -1.
(f(x) = 2/x = 2x^-1)).
Answer:
Domain = (-∞,∞)
Range = (-∞,∞)
This is a linear function.
So, if you were to graph this you'd know that it crosses the x and y axis and continues on forever without stopping.
in that case the domain and range are considered infinite on both axes.
Slope = (-5+7)/(6 - 7) = -2
y = mx + b
b = y - mx
b = -7 - (-2)(7)
b = -7 + 14
b = 7
equation
y = -2x + 7
answer
<span>a. y = -2x + 7</span>
I hope this helps you
y=x^2-81
x^2=y+81
x=square root of y+81
f^-1 (x)= square root of x+81
