Exponential rules state that when you divide exponents, you subtract by the powers. The powers have the same coefficients, so you can divide the two numbers.
Every time one x value increases the y value decreases by 4. In the x values shown the number that should come after -4 is -3 so the y values -2 and -2 that are 8 units apart should be halved and be -4. This function maintains a constant rate of change throughout the function.
Step-by-step explanation: x is the unknown number. So the unknown number (or a number) increased by 7.6, which means adding, is, or equals 9.6. hope this helps
