<h2>Sorry I was trying to explain how to plot the points but it was harder to understand without a graph</h2>
Answer:
16x^2=49 square root both sides
4x=7
x=7/4
After I read the equation, I remembered that anything to the power of 1 is itself. so f(x)=2-9
2-9= -7
therefore, f(x)= -7
if x=1, then the f(x) must be Y
<u><em>therefore, your answer should be y= -7</em></u>
Answer:

Step-by-step explanation:
divide both sides by 26 and then simplify
