Anthony was tracking the increasing number of animals in the zoo. At 9 a.m., there were 56 animals. At 11 a.m., there were 60 animals. If Anthony made the function f(x) = 2x − 38, what would the 2 represent?

The number of animals at midnight

The rate at which the number of animals was increasing

The length of time he recorded for

The total change in the number of animals

Question

Anthony was tracking the increasing number of animals in the zoo. At 9 a.m., there were 56 animals. At 11 a.m., there were 60 animals. If Anthony made the function f(x) = 2x − 38, what would the 2 represent?

 The number of animals at midnight

 The rate at which the number of animals was increasing

 The length of time he recorded for

 The total change in the number of animals

anonymous · Answer

2 is the gradient of the function at any point. So for every 1 hour, there are 2 more animals in a zoo (i.e. the number of animals increase at a constant rate of 2 animals / hour)

yea

Given the point (3, 4) and the slope of 6, find y when x = 27.

 122

 14

 141

 148

anonymous · Answer

We can use the Point-Slope form of a line:
y−yo=m(x−xo)


We were given the slope:
m=6
And a starting point,
(xo,yo)=(3,4)
And an x value,
x=27

anonymous · Answer

Plugging in our values gives us,
y−yo=m(x−xo) => y−4=6(27−3)

anonymous · Answer

27 minus 3,
y−4=6(24)

6 times 24,
y−4=144

Add 4 to each side,
y=144+4

148...
