Answer:

2

Step-by-step explanation:

In function notation, f(x) equals the y value and the x equals the x value. So this question is asking you to find the value of y when x=-2. To do this find -2 on the graph and find the point with the same x value, then find what value of y it is on. In this case, f(-2)=2.

(4x10^2) - (2x10^-1)
balandron [24]

Answer:

Step-by-step explanation:

The LCD here is 10.

Multiplying numerator and denominator of (4*10^2) by 10 results in:

40*10^3

-------------

     10

and rewriting (2x10^-1) with positive exponent in the denominator results in:

   2

---------

    10

So, before simplification, this difference comes out to be:

40000 - 2        39998            19999

----------------- = ---------------- or ------------

        10                   10                   5

Please help!! 20 POINTS

f(-3) would be 36.

When looking at synthetic division, the numbers across the top represent the coefficients of x^2, x and the constant in that order. Therefore, the equation is as follows.

2x^2 - 5x + 3

Now we can put -3 into the equation and solve.

2(-3)^2 - 5(-3) + 3

2(9) + 15 + 3

18 + 15 + 3

36
