The y intercept is what the y value is when x is 0.

Set X to 0 and solve:

-2/9(0) + 1/3

0 + 1/3 = 1/3

The y-intercept is 1/3

How to evaluate polynomial function

Katen [24]

Answer:

"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question

example: So let we are given a polynomial function as:

$f(x)=x^4+3x^3-x^2+6$ and we are aksed to evaluate this polynomial at $x=-3$

Then the value of the polynomial will be:

$f(-3)=(-3)^4+3\times (-3)^3-(-3)^2+6\\\\f(-3)=81+3\times (-27)-9+6\\\\f(-3)=81-81-9+6\\\\f(-3)=-3$

Hence on evaluating the polynomial function f(x) at $x=-3$ we get the value of the polynomial function as $-3$ .

Alexus [3.1K]

$2^{-2} = \frac{1}{2^{2} } = \frac{1}{4}$

$\frac{4}{2^{-2} } = \frac{4}{ \frac{1}{4} } = 4$ ÷ $\frac{1}{4} = 4*4= 16$
