The intercepts
The x intercepts are where the graph crosses x axis.
From the attached plot, they are:
and
These represent the start and end of the ball that is launched.
Hence, (d) is true

Answer:
A
Step-by-step explanation:
A, B, C, and D, are all functions. the " { " is saying that those functions can are different at different points. For A the function is when
and then
when
. At the point
you can see that the function on the graph is going in two different directions but it stops at
.
Based on the graph you can see that the line on the left has a slope of -1 and if it kept going it would cross the y-axis at , therefore the equation for the first line is
when
The second line on the right side has a slope of 1 and crosses the y-axis at so the equation for that line is
when
.
The only answer that matches these requirements is A
Let's start with what we know:
Smaller canvas:
Length (
) = 3ft
Width (
) = 5ft
Larger canvas:
Length (
) = ?
Width (
) = 10ft
Since these are similar rectangles, we can cross-multiply to calculate the missing length. Here's that formula:
So let's plug it all in from above:
Now we cross multiply by multiplying the top-left by the bottom-right and vice versa:
Now divide each side by 5 to isolate
The 5s on the right cancel out, leaving us with:
So the length of the larger canvas is 6 ft
