Answer: x^2 - 13x + 13
Step-by-step explanation:
In this formula, the m represents the slope of the line and the b represents the y value where x is equal to zero. This value is otherwise known as the y-intercept
When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent
When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)
