Answer:
117/78
Step-by-step explanation:
(-50-67)/(-12-56)=-117/-78=117/78
Answer:
as x approaches infinity, f(x) approaches 0
as x approaches -infinity, f(x) approaches infinity
Step-by-step explanation:
we can observe that 1/2 < 1 and since it's being exponentiated, the f(x) gets smaller and smaller as x gets bigger.
For example, f(0) = 1, f(1) = 1/2, f(2) = 1/4
so, as x approaches an infinitely large number, f(x) gets closer and closer to zero.
this is the opposite as x approaches a negatively large number. following exponential rules, 1/2^(x) = 2^x for all x < 0. therefore as x approaches negative infinity, f(x) approaches infinity.
in this case, f(-1) = 2, f(2) = 4, f(3) = 8
Answer:
Slope: 3 Y-intercept: 6
Step-by-step explanation:
You want to put this equation into y=mx+b form so it's easier to tell.
Add 3x on both sides.
y = 3x + 6
The slope is always the coefficient (number) in front of the x in the y = mx + b form. 6 is the y-intercept (reason: the y-intercept is when x=0, and when you substitute 0 for x in this, you get y=6).
