Yessssssssssssssssssssssss
Ur output value is f(x).....so to do this problem u need to sub in 2/3 for f(x) and solve for the input value which is x
f(x) = -1/3x + 7
2/3 = -1/3x + 7 ...multiply everything by 3
2 = -x + 21
2 - 21 = - x
- 19 = -x
19 = x <== ur output
The solution step by step. 43 comes from adding all the given numbers together.
Hello!
<u>What is an x-intercept</u>:
⇒ <em>value of x</em> when the <em>value of y</em> equals '0'

x-intercept is <u>25/8</u>
<u></u>
<u></u>
<u>What is a y-intercept:</u>
⇒ <em>value of y</em> when the <em>value of x</em> equals '0'

y-intercept is <u>5</u>
<u></u>
Hope that helps!

Answer:
B should be.
Step-by-step explanation:
all options, other than B have two values in set B(y) for at least 1 value of x
hence they are not functions, as a function contains unique image of x
