Please help
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

sub in 3 for x
Use BEDMAS
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
