D = Right endpoint minus left endpoint = 5 - (-8) = 13
You can take like 557divided by 59
answer : option C

Lets find the number of zeros by factoring

Group first two terms and last two terms

Factor out GCF from each group


Now we set each factor =0 and solve for x
0 = (x^2-8) and (x + 1)=0
and x = -1
and x= -1
So we have three real zeros
The function has three real zeros. The graph of the function intersects the x-axis at exactly three locations.
The given triangle is a <em><u>Right angled triangle</u></em>,
So, by applying <em><u>Pythagoras theorem</u></em><em><u> </u></em><em><u>:</u></em>
