1

because for 1 input (0 as x value), 1 output

Question 6

how to determine x intercepts for any function

Answer 6

set f(x)=0, then solve for x

Question 7

How to solve for y intercepts

Answer 7

f(0)=y

when x=0

Question 8

A function is increasing on the interval when

Answer 8

y1

Question 9

function is decreasing on the interval when

Answer 9

y1>y2

but x1

function on the interval when

Answer 10

y1=y2

for every pair of numbers x1 and x2 in the interval

Question 11

increasing function looks like

Answer 11

moves upwards from left to right as the independent variable assumes values from left to right on the interval

Question 12

decreasing function looks like

Answer 12

moves downwards, from left to right, as the independent variable

Question 13

constant function looks like

Answer 13

function value stays same as independent variable assumes values form left to right in interval

Question 14

interval

Answer 14

part of a function

how to find vertical asymptote

Answer 27

when equation is in simplified form, set denominator to 0 and solve for x

Question 28
