For y=ax²+bx+c
if a>0 then it opens up
if a<0 then it opens down
hmm, y intercept is where x=0
x intercept is where y=0
so
f(x)=3x²+4x+16
3>0 so opens up
y intercep
x=0
3(0)²+4(0)+16
16
y intercept is y=16
x intercept
0=f(x)=3x²+4x+16
there are no real solutions since the discriminant is negative
no x intercepts or no zeroes
so
opens up
y intercept of 16
no zeroes
You can use greatest common factor(gcf)
list the factors of 18 and 30.
18- 1, 2, 3, 6, 9, 18
30- 1, 2, 3, 5, 6, 10, 15, 30
now the factor that is greatest is 6.
this mean you can use the largest square tile of 6in by 6in without overlap or cutting.
Answer:
The population is increasing
Step-by-step explanation:
You can tell that function is <em>increasing</em> from the equation because <em>the rate of change</em> is 
Since this value is <em>greater</em> than 
it indicates that the population is being increased.

Answer:
Step-by-step explanation:
400 square feet
One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room, like a bathroom. Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room. This is the most common amount needed, especially when considering second coat coverage
