Answer:
Composition of f and g = 6x + 7
Composition of g and f = 6x + 11
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x + 2
f(g(x)) = 2(g(x)) + 3 = 2(3x + 2) + 3 = 6x + 4 + 3 = 6x + 7
g(f(x)) = 3(f(x)) + 2 = 3(2x + 3) + 2 = 6x + 9 + 2 = 6x + 11
Answer:
C
Step-by-step explanation:
To <u>stretched</u> f(x) = |x| <u>horizontally</u> by a factor of 6, and create the graph of g(x) we have to <u>divide the value of x</u> by 6 so the <u>y values for g(x) will be lower </u>then the y values for f(x).
2x+3(x+1.5)=12 because y=y so you SUBSTITUTE y in for y
2|x - 5| - 8 = 0
2(x - 5) - 8 = 0
2x -10 - 8 = 0
2x -18 = 0
+ 18 + 18
---------------------
2x = 18
