Best ResponseYou've already chosen the best response.2ok then ' \[f(2)=3\times 2^2+2\] what is that number?

Best ResponseYou've already chosen the best response.2think you did the "order 'o operations" wrong square first, then multiply

Best ResponseYou've already chosen the best response.2how do you square a number? multiply it by itself so \[2^2=2\times 2\]

Best ResponseYou've already chosen the best response.0so it'd be f(2)=3×2x2+2?

Best ResponseYou've already chosen the best response.2yes what is \[ 3\times 2\times 2+2\]?

Best ResponseYou've already chosen the best response.2\[g(x)=x8\\ g(\spadesuit)=\spadesuit8\\ g(\xi)=\xi 8\]

Best ResponseYou've already chosen the best response.2so how do you find \(g(2)\)? where you see an \(x\) replace it by a \(2\)

Best ResponseYou've already chosen the best response.0Gaming systems are on sale for 20% off the original price (g), which can be expressed with the function p(g) = 0.8g. Local taxes are an additional 12% of the discounted price (p), which can be expressed with the function c(p) = 1.12p. Using this information, which of the following represents the final price of a gaming system with the discount and taxes applied? c(p) + p(g) = 1.92g c[p(g)] = 0.896g g[c(p)] = 1.92p c(p) ⋅ p(g) = 0.896pg

Best ResponseYou've already chosen the best response.2lets do it with an item that cost $100

misty1212

Best ResponseYou've already chosen the best response.2first take the 20% discount, multiply \[100\times .8=80\]

misty1212

Best ResponseYou've already chosen the best response.2so it is $80 before the tax then put in the tax get \[80\times 1.12=89.6\]

Best ResponseYou've already chosen the best response.2what did we do? first multiply by \(.8\) then multiply by \(1.12\)

Best ResponseYou've already chosen the best response.2i see what they want you to say, they want you to pick B

misty1212

Best ResponseYou've already chosen the best response.2first do \(p\) then do \(c\) it is \[c(p(g))\]

misty1212

Best ResponseYou've already chosen the best response.2which is kind of silly since you can do it just by multiplying, but whatever pick B
