The
first graph.
The equation is x - 1

3
In order to solve it, you need to get x by itself.
Add 1 to both sides. 3+1=4
x

4
Since this is your sign

the arrow has to point towards the left, and the circle needs to be colored in.
D. q(x)
it is the only exponential function
y is multiplied by 2 each time c increases by 1
There is a formula for adding consecutive numbers:
total = n*(n+1)/2
total = 80*(81)/2
total = 3,240
There are always 180° in a triangle, so to work out the missing angle, you add up the angles you have and do 180 - that answer.
So it would be:
79 + 37 = 116
180 - 116 = 64.
y = 64 :)
