Answer:
Lower left.
Step-by-step explanation:
To determine if a graph is a function the "vertical line test is used. If any point on a graph has one x value go to two y values it is not a function.
Witht he four pictures, the two on the right use a horizontal line, so it doesn't tell at all, on the leftthe upper one is vertical but it doesn't show that one x value has two corresponding y values. So it must be the lower left one.
The lower left picture has a line at x=1, and it passes through the line of the graph at two different y values, 4 and -4. So this has two y values with one x value.
Obviously the oppisite of a negative number is gonna be a positive number, it’s 8
<u><em>-26-15i is the right answer.</em></u> First you had to multiply by the parenthesis and you can also apply complex arithmetic rule. And it gave us, , and it gave us the answer is <em><u>=-26-15i is the right answer. </u></em>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
-5c^2-3c+4 This polynomial is in standard form, now, and the leading coefficient is 5, because it is the coefficient of the first term. Degree is 2, due to -5c^2.
Move (and change the sign of) the number term on the left to the other side to lleave q alone>>> here you will get choice number 1
