Question

Graph each function using the given values of x. Use the graph to determine the domain and range of the function.


1a. f(x) = x2 + 3; x = -3, -2, -1, 0, 1, 2, 3


1b. g(x) = ; x = -2, -1, 2, 7


1c. h(x) = |x + 2|; x = 0, 1, 2, 3, 4, 5, 6


1d. f(x) = -5; x = -3, -2, -1, 0, 1, 2, 3


1e. g(x) = x3 + 4; x = -2, -1, 0, 1, 2

Ok so I am suppose to help someone solve these and I don't know how, i basically need like an answer key lol but I need to know by tmrw and am sorta clueless, I don't even remember learning this lol

Answer 1

or can someone just show me how to solve these, please!!!!!!!!!!

Answer 2

@jim_thompson5910
@Luigi0210
@Loser66
any of you guys remember these?

Answer 3

all of them? o.O

Answer 4

just one and I will do the rest by ur example

Answer 5

@Luigi0210

Answer 6

cuz tmrw I need to sorta have an idea how to solve these

Answer 7

here is the easiest one
\[ f(x) = -5; x = -3, -2, -1, 0, 1, 2, 3\]
\(f(-3)=-5, f(-2)=-5, f(-1)=-5, f(0)=-5, f(1)=-5,f(2)=-5, f(3)=-5\) points on the graph are
\[(-3,-5),(-2,-5),(-1,-5),(0,-5),...\]

Answer 8

\[1a. f(x) = x^2 + 3; x = -3, -2, -1, 0, 1, 2, 3 \]
\[f(-3)=(-3)^2+3=9+3=12\]
\[f(-2)=(-2)^2=4+3=7\]
\[f(-1)=(-1)^2=1+3=4\] etc etc

Answer 9

just sub in values and see the value of the function and graph

Answer 10

brb

Answer 11

ty so much!!!!!!!!!!!!

Answer 12

@luigi can we do 1b. and then we can compare answers?
