f(x) = 3x² + 2

x= 3

my question, do I start by solving x² first then multiply by 3 and adding 2

f(3= 3 * 9 + 2 = 29

or do I multiply first

3*3 =9² +2 = 83

I'm pretty sure we resolve the exponents first but need some help

B - brackets, (if any)

E - exponents

D - divisions in the order they occur

M - Multiplications in the order they occur

A - Additions in the order they occur

S - Subtraction in the order they occur

Yes, you are correct in the order you did the calculation the first time

f(3) = 3(3^2) + 2

= 3(9) + 2

= 27+2

= 29
