Maksim231197 [3]

Answer:

x<3 and x<5

Step-by-step explanation:

Given the quadratic inequality x² - 8x + 15 <0, to get the solution set for the inequality, the following steps must be followedStep 1: Factorize the quadratic expression

x² - 8x + 15 <0

x² - 3x - 5x + 15 <0

x(x - 3) - 5(x - 3) <0

(x -3)(x -5)< 0

x -3<0 and x -5<0

x< 3 and x< 5

Describe and correct the error a student made in writing an exponential function

NemiM [27]

Answer:

we CANNOT DIVIDE 3 with 6.

Step-by-step explanation:

Here,as given in the question:

Starting value = 6

Constant ratio = 1/3

Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.

⇒ f(x) = (Starting value) x (ratio)... x times

$\implies f(x) = 6 (\frac{1}{3} )^x = 6 (\frac{1}{3} ) (\frac{1}{3} ) (\frac{1}{3} ) .... x$

Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.

Hence, $\implies f(x) = 6 (\frac{1}{3} )^x$ and $f(x) \neq 2^x$
