The axis of symmetry of the graph of y = -(x+4)2 -6 is
a. x = 6
b. x = 4
c. x = -4
d. x = -6

i'm fairly sure it's d, but i'm rubbish at maths : (

Anyone know? will mark brainliest if correct!

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities

Multiply and simplify. 2x^2 y^3 z^2 · 4xy^4 x^2 i will mark you brainliest if right. show how you got the answer, !
