F(x)=4x2-3x+5 f(2) find function value
Dovator [93]

Hello!

This question is an example of function notation. Function notation is basically f(x) , said as "f of x". To solve this problem, you need to substitute x = 2 into each x-value in this equation. F(2) is written as function notation, while x = 2 is not.

F(2) = 4x² - 3x + 5

F(2) = 4(2)² - 3(2) + 5

F(2) = 4(4) - 6 + 5

F(2) = 16 - 6 + 5

F(2) = 15

Therefore, the value of F(2) is 15.

35% of what number is 35? <br> Please solve all steps using a=p•w
son4ous [18]
35% * X = 35
first you would change 35% to .35
then the equation would be .35 * X = 35
next you would divide .35 from both sides making the equation- 
x = 100

then to check plug it in 
.35 * 100 = ?
.35 * 100 = 35
want me to message you how to i did it?

What does "Classify the polynomial by the number of terms" mean
soldier1979 [14.2K]

"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like 2x^{2}.

A binomial has 2 terms like 3x^{2}+6x

A trinomial has 3 terms like 4x^{2}+5x-8

And a polynomial has 4 or more terms.

So basically one can classify the type of polynomial by counting the number of terms in a given equation.
