Answer:
3. domain: {-5, -3, 0, 1, 2}; range: {0, 1, 2, 3}. <u>Is</u> a function.
4. <u>Is no</u>t a function.
Step-by-step explanation:
3. You don't need to list range values twice. Domain and range values are correct otherwise.
The relation is a function, because each domain value is used only once.
__
4. The relation is not a function, because the domain value 4 maps to two different range values. A function can only be single-valued: each domain value maps to exactly one range value.
Should be the first one. All you have to do is plug in the x-value for each set of pairs into each equation. If the equation fits the points, then the y-value should match the y.
2(4x³ + 9m + 3x²)
2(4x³) + 2(9m) + 2(3x²)
8x³ + 18m + 6x²
