1. The rule is that for something to be a function, one input(x-value) can ONLY HAVE ONE output(y-value). If one input has more than one output, it is not a function. Your answer is #1 because you can only have 1 output
2. Since you've been given the input -> x = -10, substitute/plug it into the equation to find the output:
Plug in -10 into "x"
y = -15 + 6
y = -9 Your answer is #2
Answer
21/2:3 and 16:6 are not equivalent
Answer:
Option C. f(x) and g(x) are the same when x = 2.
Step-by-step explanation:
step 1
Find the value of f(x) for x=2
we have
For x=2
Substitute in the function
step 2
Find the value of g(x) for x=2
Observing the graph
For x=2 ----> the value of g(2)=3
step 3
Compare the values
f(2)=3
g(2)=3
therefore
f(x) and g(x) are the same when x = 2.
A=49.44
B=232.91
C=-283.29
(49.44-232.91)+(-283.29)=-466.76
-283-(232.91+49.44)=-565.35
