If the graph of the function y=h(x) contains the point (5,-4) then which of the following must be true A.) h(-4)=5
B.) h(5)=-4
C.) Tue graph of y=h(x) must be a straight line
D.) h(x)=5 for every real number x

B

Step-by-step explanation:

(x, y) --> y = h(x)

(5, -4) --> -4 = h(5)

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2

=240

=48
