Answer:
34
Step-by-step explanation:
1)
i) Reflection about y axis i.e. x=0
ii) Horizontal shrink by scale factor 4
iii) vertical shift by 4 units up.
-----------------------------------
2) f(x) passes through (1,-1) and (0,1)
So slope = (1+1)/(0-1) = -2
Using point slope form equation of f(x) is
y-1 = -2 (x-0) or y = -2x+1
g(x) passes through (0,-1) and (1,1)
Slope = (2/1) = 2
So using point slope form g(x) is
y-1=2x
Hence we find that y-1 = -2x is transformed into y-1 = 2x
i.e. there is a reflection of f(x) on the line y =1
-------------------------------
Answer: c = -2
Explanation:
-2c + 6 = 10
-2c = 10 - 6
-2c = 4
c = 4/-2
c = -2
Y=3x+1
to find the slope, find the change in y/change in x
7-1=6
2-0=2
6/2=3
3 is your slope
your y intercept occurs when x=0, and that was given to you in the problem
(0,1)
your y int is 1
y=3x+1
