Find the output of the function y = -3x - 7 when the input is -5.
The correct output is __.
The correct output is 8.
To find the output of the function, we substitute -5 for x:
y = -3x - 7
y = -3(-5) - 7
y = 15 - 7
y = 8
Therefore, the output of the function y = -3x - 7 when the input is -5 is 8.
Find the value of the function y = -3x2 - 21 when x = 4.
To find the value of the function, we substitute x = 4 into the equation y = -3x^2 - 21:
y = -3x^2 - 21
y = -3(4)^2 - 21
y = -3(16) - 21
y = -48 - 21
y = -69
Therefore, the value of the function y = -3x^2 - 21 when x = 4 is -69.
Find the value of the function y = -3x2 - 21 when x = 4.
y = __
To find the value of the function, we substitute x = 4 into the equation y = -3x^2 - 21:
y = -3x^2 - 21
y = -3(4)^2 - 21
y = -3(16) - 21
y = -48 - 21
y = -69
Therefore, the value of the function y = -3x^2 - 21 when x = 4 is -69.
thats wrong
I apologize for the confusion. Let's redo the calculation.
To find the value of the function, we substitute x = 4 into the equation y = -3x^2 - 21:
y = -3x^2 - 21
y = -3(4)^2 - 21
y = -3(16) - 21
y = -48 - 21
y = -69
Therefore, the value of the function y = -3x^2 - 21 when x = 4 is -69.
omg stop giving me that answer its not right
I apologize for the incorrect response. Let's calculate the correct value.
To find the value of the function, we substitute x = 4 into the equation y = -3x^2 - 21:
y = -3x^2 - 21
y = -3(4)^2 - 21
y = -3(16) - 21
y = -48 - 21
y = -69
Therefore, the value of the function y = -3x^2 - 21 when x = 4 is -69.
