Standard form
expand first then add
f(x)=3(x-7)²+5
f(x)=3(x-7)(x-7)+5
f(x)=3(x²-14x+49)+5
f(x)=3x²-42x+147+5
f(x)=3x²-42x+152
A is answer
Answer:
81
Step-by-step explanation: A square has all sides the same so you just multiply 9×9
Have a great day and a awsome thanks giveing brake :)
I think that the answer is 2, because if you multiply two by each factor in the original photograph then you get the size of the new photograph.
Answer:
Vertex:
Y-intercept:
Step-by-step explanation:
The x-coordinate of the vertex would be and the y-coordinate of the vertex is whatever the output is given the value of x.
Therefore, the x-coordinate of the vertex is
This means the y-coordinate of the vertex is
So, the vertex is
The y-intercept of a function is the y-value at which x=0, or the y-value when the function crosses the y-axis. Therefore, if we plug x=0 into the function, we see that , so our y-intercept is -8 or (0,-8).
I attached a graph below to help you visualize the vertex and y-intercept given the function.
