Why is a fixed interest rate almost always better than a variable interest rate?

Fixed interest rate is the interest rate on loans that does not change during the fixation period. It is typical of short-term and medium-term loans and is guaranteed throughout the maturity of the loan. The fixed interest rate is entered into with the relevant bank in the form of a contract that guarantees the fixed amount of agreed installments throughout the agreed period.

The fixed interest rate is always better than the variable interest rate because it guarantees to the one who obtained the loan or made the investment a security in the money that should be paid or obtained as a result of the operation, and does not subject that amount to external factors that can affect this interest rate if it was variable.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
