Domain and
What is a dicrete domain?
A discrete domain is a set of input values that consists of only certain numbers in an interval.
is this a linear or nonlinear function , y=5x?
Linear
Evaluate f (x) = −4x + 7 when x = 2.
When x = 2, f (x) = − 1.
What is the range of the function y=5x+4 if the domain is 0,1,2,3?
4,9,14,19
What is a continuous domain?
A continuous domain is a set of input values that consists of all numbers in an interval.
What is the equation of a linear function?
Y= mx+b
What is the equation for function notation?
f (x) = mx + b
What is the range of the function y=1/2x if the domain is 2,4,6,8
1,2,3,4
What is evaporation?
When water turns into air.
For h(x) = 2 — 3 x − 5, find the value of x for which h(x) = −7.
When x = − 3, h(x) = − 7.
What is the domain of the function y=8x+4 if the range is 4,12,20,28
0,1,2,3
What do we have in common with a playtapus?
We both breath oxygen; We both go through the cell cycle; We both have to have food, water and living space
Graph g(x) = x − 3. Compare the graph to the graph of f (x) = x.
The graphs have the same slope but different y-intercepts. The graph of g is a translation 3 units down of the graph of f.
If a domain is 2,4,6,8 and a range is 3,5,7,9, what is the function?
Y=x+1
Graph f (x) = 2x + 5.
X:-2,-1,0,1,2
F(x):1,3,5,7,9
