Answer:
7
Step-by-step explanation:
There is a point of inflection at each point where the graph crosses the line y=2. There are 7 points of inflection shown.
__
A point of inflection is where the graph changes from being concave downward to concave upward, or vice versa. For a sine function, that is everywhere the function crosses its midline.

Convert equation to standard form

Answer:
y=-1/10 x - 41/10
Step-by-step explanation:
slope: y2-y1 / x2-x1 = -5-(-4) / 9-(-1) = -1/10
y= -1/10 x +b, substitute (-1,-4) to solve b
-4=-1/10 (-1) +b
b=-41/10
34 x 47 = 1598 so that’s the range
For a 7*7=49 so sqrt(49)=7
6*6=36 so sqrt(36)=6
and since sqrt(x) is am increasing function then
6 < sqrt(42) <7
you do the same for b but with 4 values :
like 4*4*4= 64
and 3*3*3=27
