If f(x) = 1/3x^2 + 5, find f(-9).<br> A. 248<br> B. -22<br> C. 11<br> D. 32

melamori03 [73]

Answer:

D. 32

Step-by-step explanation:

For this problem, we simply plug -9 in for x in f(x):

$f(x)=\frac{1}{3} x^2+5$ ⇒ $f(9)=\frac{1}{3} *(9^2)+5=\frac{1}{3} *81+5=27+5=32$

Thus, the answer is D. 32.

Hope this helps!

How do you determine where f(x)=cos^(-1)(lnx) is continuous?

olga nikolaevna [1]

$\ln x$ is continuous over its domain, all real $x>0$ .

Meanwhile, $\cos^{-1}y$ is defined for real $-1\le y\le1$ .

If $y=\ln x$ , then we have $-1\le \ln x\le1\implies \dfrac1e\le x\le e$ as the domain of $\cos^{-1}(\ln x)$ .

We know that if $f$ and $g$ are continuous functions, then so is the composite function $f\circ g$ .

Both $\cos^{-1}y$ and $\ln x$ are continuous on their domains (excluding the endpoints in the case of $\cos^{-1}y$ ), which means $\cos^{-1}(\ln x)$ is continuous over $\dfrac1e$ .
