|PRE-CAL MATH TEST|
Show all your work. Write neatly and clearly.
1)Test the following to see if they are functions. If they are
|i) state one-to-one or many-to-one||ii) state the domain.|
If they're not, say why.
|a) x = y 2||b) y = x2 3x 28||c)|
2) Write the equation of the line:
3) State the slope, y-intercept and x-intercept of 2x + 3y =24
1) y = 2x2 60x + 25
2) Find the x-intercepts or ZEROS (if any) for:
|a) y = x2 5x||b) y = x2 4x 21||c) y = x2 4x + 5|
3) A farmer has 60 meters of fencing to enclose a rectagular field along a riverbank.
The side along the river needs no fence since his cows can't swim.
What dimensions should he make the field in order enclose a maximum area?
