Answer:
4x^2 - 4x - 3
Step-by-step explanation:
f(x) = 2x - 1
g(x) = x^2 - 4
g(f(x)) = ?
[substitute the x of g(x) with f(x)]
g(x) = x^2 - 4
g(f(x)) = (2x - 1)^2 - 4
[solve]
[binomial * binomial = quadratic equation]
[use FOIL method (first, outer, inner, last)]
g(f(x)) = (2x - 1)(2x - 1) - 4
g(f(x)) = (2x*2x) + (-2x) + (-2x) + (1) - 4
[combine like terms]
g(f(x)) = 4x^2 - 2x - 2x + 1 - 4
g(f(x)) = 4x^2 - 4x - 3
Answer:
C) y = 2x + 3
Step-by-step explanation: You have to substitute 1 for x & 5 for y & 2 for m, but 1st do the point slope form ---> slope intercept form.
y -Y1 = m(x - X1)
y - 5 = 2(x - 1)
y - 5 = 2x - 2
+5 + 5
y = 2x + 3 --- IN SLOPE INTERCEPT FORM
Hope this helps you!!! :)
Hello!
Explanation:
Slope-intercept form: → 
m: represents the slope and is constant.
b: represents the y-intercept.
Rise/run.
<u><em>Y-intercept is -7</em></u>
<u><em>But the slope is -5.</em></u>
<u><em>Answer: → 0.714</em></u>
Hope this helps!
