If g(x) = 2 − 1, what is g(−2.3)?
A) -7
B) -5
C) -4
D) -3

-5.6

Step-by-step explanation:

Let the given function be g(x) = 2x - 1

To get g(-2.3), you will substitute x = -2.3 into the expression as shown;

g(x) = 2x - 1

g(-2.3) = 2(-2.3) - 1

g(-2.3) = -4.6 - 1

g(-2.3) = -5.6

Hence the value is -5.6

Note that the function was assumed. Same procedure can be applies for any function g(x).

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
