Answer: choice A) -4
-----------------------------------------------
Step 1) Draw a vertical line through 1 on the x axis
Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)
Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis.
So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.
In short, this is why f(1) = -4
By factorising a function, you can find the value of x-intercepts by substituting f(x)=0
By plotting a graph, you can check the values of x-intercepts
Answer:
p(4) = $10.69
p(14) = $20.79
p(14) - p(4) = $10.10
p( 14) - p(4)/14-4, and interpret this result
$1.01 This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.
Step-by-step explanation:
The average ticket price for a baseball game, in p years after 1991, can be modeled by the following equation:
Find p(4).
Find p(14).
Find p( 14) - p(4).
20.79 - 10.69 = 10.10
Find p( 14) - p(4)/14-4, and interpret this result.
10.10/10 = 1.01.
This is the yearly average rate that the ticket price changed during this interval. This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.
$75= Cassidy's goal
c= number of cupcakes
a= $6 already raised
EQUATION:
75<$3c + a
substitute $6 in for a
75< $3c + 6
subtract 6 from both sides
69<3c
divide both sides by 3
23<c
Cassidy needs to sell at least 23 cupcakes to reach her goal of $75.
Answer:
FALSE: Cassidy will need to sell any number of cupcakes greater than 12 to reach her goal.
TRUE: Cassidy will need to sell any number of cupcakes greater than 23 to reach her goal.
