PLEASE HELP WITH THIS ONE AS WELL! I’m struggling with Transcendental Functions!

$h(x)=20e^{kx}$

a. If $h(1)=20$ , then $20=20e^k\implies e^k=1\implies k=0$ .

b. If $h(1)=40$ , then $40=20e^k\implies e^k=2\implies k=\ln2$ , so that $2k+1=2\ln2+1$ .

c. If $h(1)=10$ , then $10=20e^k\implies e^k=\dfrac12\implies k=-\ln2$ , so that $k-3=-\ln2-3$ .
