Question

Help with functions??

I am having trouble solving this because I am not good with fractions!

f(1/3)= 4(1/3)^2-5(1/3)+2

Answer 1

[4*(1/3)*(1/3)] - [5*(1/3)] + 2
= (4*1/9) - (5/3) + 2 (from here you find the least common denominator, which is 9. therefore, every fraction will be over 9
4/9 is already over 9
5/3-> 15/9, as you multiply by 3/3 (which is the same as multiplying by 1)
2 -> 18/9, as you multiply by 9/9 (which is the same as multiplying by 1)

= 4/9 - 15/9 + 18/9
= 7/9
