A2: Unit 5 Section 1 Lesson

Why I stopped the video

On the last question I got a little messed up when it came to the domain, and I need to talk to another math teacher to make sure I am correct. I will add a short video to tomorrow's lesson explaining what I got confused on!

Multiple Choice

If g(x) = 6x + 4 and f(x) = 3, find f(x) * g(x)

• 18x + 4

• 9x + 7

• 6x + 7

• 18x + 12

Multiple Choice

f(x)=x³-3x
g(x)=-4x+1
Find f(x)*g(x)

• -4x³-5x²-3
• -4x³+2x²-3x
• -4x⁴+x³+12x²-3x
• -4x^4-x³+12x²⁺3x

Multiple Choice

f(n)=2n+1
g(n)=3n
Find f(n)+g(n)

• 5n+1
• -5n+1
• -2n+1
• -6n-1

Multiple Choice

f(x) = x²+9

g(x) = x-9

Find f(x)-g(x).

What is the domain?

• $\left(-\infty,\infty\right)$

• $x=0$

Classwork

Complete 1-12 on the classwork that is attached. I will have the whole notebook ready to download this afternoon. If you want a printed copy please let me know, and I will take one to the office for you.
