Please help, Describe the transformation of the graph of the parent function y = √x for the function y = √x + 7 + 5.
Setler79 [48]

Answer:

C. Up.

Step-by-step explanation:

We have been given that the parent function y=\sqrt{x} is transformed to the function y=\sqrt{x+7}+5. We are asked to describe the given transformation.

Let us recall the transformation rules.

f(x+a)=\text{Graph shifted to left by a units},

f(x-a)=\text{Graph shifted to right by a units},

f(x)+a=\text{Graph shifted upwards by a units},

f(x)-a=\text{Graph shifted downwards by a units}.

Upon comparing our transformed function with the parent function, we can see that the graph is shifted to left by 7 units and upwards by 5 units.

Therefore the correct choice is option C.

For what value of a do the lines 5x–2y=3 and x+y=a intersect at a point on the y-axis?
inna [77]

Answer:

  a = -3/2

Step-by-step explanation:

You can set x=0 and solve for y to find the y-intercept in each case.

  first equation: y-intercept = -3/2

  second equation: y-intercept = a

To make these equal, we must have ...

  a = -3/2
