Part A: yes, because every input value x produces only one output value y.
Part B: in the first function, when x=7, why=8 is given
in the second function, when x=7, y=2x+13=27
so the second function has a greater value when x=7
Part C: when f(x)=2x+13=75, 2x=62, x=31
Answer:
C) 0.8
Step-by-step explanation:
To find the x-intercept of a given linear equation, plug in 0 for 'y' and solve for 'x'. To find the y-intercept, plug 0 in for 'x' and solve for 'y'. I hope this helps and have a great day (Also brainliest would be appreciated but you don’t have to) :)
