Given the function f(x) = 4(2)x, section a is from x = 1 to x = 2 and section b is from x = 3 to x = 4. part

A. Average rate of change for x=1 to 2: 4(2²)-4(2)=16-8=8; from x=3 to 4: 4(2⁴)-4(2³)=64-32=32.
b. Section b is 32/8=4 times greater. As the exponent of 2 increases, the gaps between consecutive powers of 2 gets wider and therefore the rate of change is greater.

1. y-axis 2. y-axis 3. x-axis 4. x-axis (i can’t really see it but i think it’s x) 5. x-axis 6. y-axis 7. y-axis 8. x-axis (the reason why it’s either x or y axis is bc it’s either going up and down or left to right.)

Amery drives 50 miles in one hour. How many miles does he drive in 2.25 hours?

slavikrds [6]

So if he drives 50 miles in 1 hour, then he must drive 100 miles in 2 hours. 0.25 is another way of writing 1/4, and to find 1/4 you divide by 4, so 50 ÷ 4 = 12.5 miles. Then you can add this to 100 and get your answer as 112.5 miles.
If you have a calculator, or if you're allowed a calculator, then a simpler way is to just do 2.25 × 50 = 112.5
Hope this helps!
