You found it out already but yeah
Answer:
y = (2/7)x - 7
Step-by-step explanation:
Answer:
The domain is (-∞,∞) and range is (k,∞)
Step-by-step explanation:
The graph is given as
.
When x =0, we have f(x)
= y intercept
Consider the exponential function y =
.
This is defined for domain all real numbers and range = (0,infinity) for all positive a.
This function is transformed into our function by horizontal shift of h units to left and vertical units of k units up.
i.e. Y = y-k and X = x-h
Since x has domain as set of all real numbers X also set of real numbers
So domain is (-∞,∞)
Since range of original graph is (0,∞), we have Y minimum value as k and max as infinity.
Range = (k,∞)
Answer:
8
Step-by-step explanation:
When a number is put in the parenthesises with x you substitute that number in every time you see x.
f(x)=5x-7
f(3)=5(3)-7
f(3)=15-7
f(3)=8
