How do I figure out b,c, and d
2 answers:
Step-by-step explanation:
From the graph:
a) f(3) = ?
The vertical line x = 3 intersect the parabola in the point (3, -1).
Therefore f(3) = -1
b) The domain: the set of all real numbers (R) ⇒ x ∈ (-∞, ∞)
c) f(x) = 3, x = ?
The horizonatal line y = 3 intersect the parabola in the point (1, 3) (vertex).
Therefore x = 1 (f(1) = 3.
d) The domain: y ≤ 3 ⇒ y ∈ (-∞, 3]

Answer:
The difference in slopes of is = 3
We can say slope of is positive and 3 more than slope of
while slope of
is negative.
Difference of y-intercepts of is = -7
We can say the y-intercept of is positive and 7 units above
while y-intercept of
is negative.
Step-by-step explanation:
Given equation:
We need to find the difference of slopes and y-intercepts of the given equations.
The standard form of a slope intercept equation of line is given by:
where represents slope and
represents y-intercept of line.
Writing the given equations in standard form to find slope and y-intercept.
Slope = 2 and y-intercept =-2
Slope = -1 and y-intercept =5
The difference in slopes of is =
We can say slope of is positive and 3 more than slope of
while slope of
is negative.
Difference of y-intercepts of is =
We can say the y-intercept of is positive and 7 units above
while y-intercept of
is negative.
