Answer:

g(x) = 4x + 4

Step-by-step explanation:

The given function is f(x)=x.

If we stretch vertically by a factor of 4 and a translation of 4 units up then the new function becomes

g(x) = 4f(x) + 4

But f(x)=x

We substitute to obtain the equation of g(x) as

g(x) = 4x + 4

Answer:

g(x) = 4x + 4.

Step-by-step explanation:

f(x) = x

Vertical stretch gives  4x.

A translation of 4 up gives 4x + 4.

What is the y-intercept of the line perpendicular to the line...
Dominik [7]

Answer:

D) 5

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes.

The line: y=\frac{3}{4} x+3 has a slope of \frac{3}{4} as it is  in y=mx+b form, where m is the slope, and b is the y-intercept.

Since the slope is \frac{3}{4}, we see that the negative reciprocal slope is -\frac{4}{3}, as \frac{4}{3} is the reciprocal (flip the numerator and denominator).

From here, we can use point slope form: y - y1 = m(x- x1), where (y1, x1) is  the point. In this case, (3, 1) is the point.

Thus, we have: y-1 =-\frac{4}{3}(x-3) as our final equation.

Simplifying: y-1 = -\frac{4}{3}x+4

And: y=-\frac{4}{3}x+5, which gives us the y-intercept to be 5.

Let me know if this helps!
