Answer 1

Here's your answer....

Answer 2

Answer:

The value of the given expression is when x=0 value is 1 and if x=-0.25 value is 0.

Step-by-step explanation:

Given : Expression $1+9x+27x^2+28x^3$

To find: The value of given expression?

Solution : $1+9x+27x^2+28x^3$

We solve the given expression with the help of the graph.

Let $y=1+9x+27x^2+28x^3$

Now, we plot the graph of the given equation and see the x-intercept and y-intercept which are the solutions of the given equation.

Refer the attached figure below.

We see that,

The intersection points to x axis is (-0.25,0)

The intersection points to y axis is (0,1)

Therefore, The value of the given expression is when x=0 value is 1 and if x=-0.25 value is 0.
