we know that
Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph
So

in this problem

substitute the values in the formula above

Divide by
both numerator and denominator

therefore
the answer is

as the function is polynomial domain exist for all real number ie (-infinity to + infinity) but range exist (0 to +infinity ) due to modulus negetive range do not exist
False, 34° celcius is NOT equal to 0° Fahrenheit. It is 93.2°F
6.23+ -12.49 -2.6= 6.23+ -12.49+ -2.6
-6.26+-2.6= -8.86
