IrinaVladis [17]

Answer:

$f(h(-1))=-11$

Step-by-step explanation:

Given:

$\begin{aligned} &f(t)=\dfrac{2t+7}{t-3} \\\\ &h(n)=-2n^2-3n+1 \end{aligned}$

We want to determine the value of $f(h(-1))$

First, we evaluate h(-1)

$h(-1)=-2(-1)^2-3(-1)+1 =-2+3+1\\h(-1)=2$

Therefore: $f(h(-1))=f(2)$

$f(2)=\dfrac{2(2)+7}{2-3}\\=\dfrac{4+7}{-1}\\=-11$

Therefore: f(h(-1))=-11

Is it possible for the absolute value function to have negative values?

Amiraneli [1.4K]

Answer:

Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.
