How many x intercepts appear on the graph of this polynomial function? f(x)=x^4-5x^2 1 x intercept 2 x intercepts 3 x intercepts
Bumek [7]
You can find the number of x intercepts by setting f(x) equal to zero giving you 0=x^4-5x^2. You can factor out an x^2 and divide on both sides (when you divide 0 by anything it is still zero so the x^2 disappears), and you are left with 0=x^2-5, which you can solve easily giving you x=+/- sqrt(5). However, the original equation also has an x intercept at (0,0) which you can see by plugging 0 in for x. So the grand total of x intercepts is 3!

After m months, the height of a plant is 10 + 3m millimeters. How tall is the plant after eight months? three years?
mr_godi [17]
Height for m months = 10 + 3m millimeters

You basically just have to plug in the number of months in the variable m.

So for 8 months

Height for 8 months = 10 + 3x8 millimeters
Height for 8 months = 10 + 24 millimeters
Height for 8 months = 34 millimeters

For 3 Years.
There are 12 months in 1 year.
For 3 years there are 12 x 3 = 36 months

Plug it into the equation
Height for 36 months = 10 + 3x36
Height for 36 months = 10 + 108
Height for 36 months = 118 millimeters
