F(x)=(1÷4)^x Is it and Incease,decrease or constant
Fynjy0 [20]

Answer:

Decrease

Step-by-step explanation:

The general form of exponential functions is a · b^x^-^h +k. If b, or the base with the exponent, is bigger than 1, than the graph increases, experiencing growth. If the base is somewhere between 0 and 1, then the graph decreases, experiencing decay.

\frac{1}{4} is a number in between 0 and 1, thus the graph would decrease.

How would you use estimation to evaluate this expression: 10.2 × [(2×3.7)+8]
tresset_1 [31]
Well, first you would estimate all the terms: 10.2 to 10, 2 to 2(keep the same), 3.7 to 4, and eight to eight.

So you have 10 x [(2 x 4) + 8]
then you would evaluate this expression using order of operations
 
10 x [(2 x 4) + 8]
10 x [8 +  8] 
10 x 16
