Think about this as a table of values where domain is the x values and range is the y values.
f(4) wants the y-value when the x-value is 4
f(4) = 1/2
The second question wants us to find the x-value when f(x) also known as the y-value is 4.
f(x) = 4
x = 8
answers: 1/2, 8
Answer:
Step-by-step explanation:
y=mx+b
y less than or equal to -3x-23
Answer:
y = -3x+8
Step-by-step explanation:
formula = y=mx+b
slope is m
y-intercept is b
Answer:
(3/5)x+1/4=(3/4)x-2/5
<=> (3/5)x - (3/4)x= -2/5 - 1/4
<=> x(12/20 - 15/20) = -13/20
<=> x(-3/20) = -13/20
<=> x = 13/3
Step-by-step explanation:
the answer is 4
just think of -4 as 4 in this question it is looking for the one closer and now that both of them are counting numbers 4 is less
