Answer:
f(x) = 2x - 7
Step-by-step explanation:
Plug in the numbers on the right and see what answer is right
f(x) = 2x(1) - 7=-5
f(x) = 2x(2) - 7=-3
f(x) = 2x(3) - 7=-1
f(x) = 2x(4) - 7=1

First of all we need the line equation so let's find it first :
y = mx + b
y = 2x + b
_______________________________
The line passes through point ( 8 , 3 ) which means if put 8 instead of x the y must equals to 3 :
2(8) + b = 3
16 + b = 3
b = 3 - 16
b = - 13
______________________________
Now we have the equation of the line :
y=2x-13
To find the y-intercept we just need to out 0(zero)instead of x; Let's do it :
y = 2(0) - 13
y = 0 - 13
y = - 13
Thus the y-intercept=-13
Answer:
the y intercept is -13

Step-by-step explanation:
The graph of f(x) = x2 is shifted left 3 units.
The graph of f(x) = x2 is shifted up 30 units.
The graph of f(x) = x2 is reflected over the x-axis.
Using translation concepts, it is found that the correct option is given by:
The graph of f(x) = x² is shifted left 3 units.
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, we have that the original function is:
f(x) = x².
The translated function is:
g(x) = 4x² + 24x + 30.
Factoring it we have that:
g(x) = 4(x² + 6x + 7.5) = 4[(x + 3)² - 1.5].
Since x -> x + 3, the function was shifted left 3 units.
