Let's define what as 'x'
3x = 75
Divide both sides by 3.
3x/3 = 75/3
x = 75/3
x = 25
Three times twenty five equals 75.
Your final answer is twenty five or 25.
Put both values into a ratio
P:B
28:79
F(-1) = 3
How did I figure this out?
f(-1) is substituted for f(x) so you must look at -1 on the x axis.
Once you've located -1 on the x-axis, locate what it equals to answer the question.
The answer should be the y-axis number that corresponds to -1 which is 3.
