I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)
Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original<span />
Answer:
the answer should be D. it's been awhile since i did middle school math XD
Answer:
g(x) is the image of f(x) after stretched horizontally by scale factor = 4
Step-by-step explanation:
The statement that best compares the graph of g(x) with the graph of f(x) says g(x) is the image of f(x) after stretched horizontally by scale factor = 4 because:
Given the function
f(x) = x² and g(x) = (1/4x)² the image of f(x) after one transformation.
The transformation shows that g(x) stretches away from y-axis.
Since the transformation is stretched horizontally. So g(x) is the image of f(x) after stretched horizontally by scale factor (I.e. by 1).
Then we use the scale factor to divide g(x)
1 ÷ ¼ = 1 x 4/1 = 4
So therefore, g(x) is the image of f(x) after stretched horizontally by scale factor = 4
Answer:
Height equation for first student is correct while that of second student is incorrect.
Step-by-step explanation:
Given that the function of height should be quadratic function.
Standard form of Quadratic function is given as,
.
Degree of quadratic function is 2.
Equation of height for first student is given as 
Since, above equation has degree 2 and equation is in quadratic form with value of b and c as 0.
Therefore, height equation for first student is correct.
Equation of height for second student is given as 
.
Since the degree of above equation is 1, hence it cannot be the quadratic function. Hence second equation is not an quadratic function.
Therefore, height equation for second student is incorrect.
