What t value will yield 4?
H(t) = 4t + 20
How about -4?
H(-4) = 4(-4) + 20
H(-4) = -16 + 20
H(-4) = 4
Yes, t = -4
Done.
You are told 2/9 = 16
Let total number of batteries = x
So you now have 2/9x = 16
To find x divide both sides by 2/9
X = 72 total batteries
Domain: The set of possible values of x
Range: The set of possible values of y
Zeros: The x-intercepts (what value of x is on the x-axis)
Discontinuities: Where the graph stops (and restarts somewhere else)
Asymptotes: The graph cannot cross this line (vertical, horizontal, oblique)
Because they're both slant like and they both is like you're going down a hill
