Simplify to get your answer

The answer is $\frac{9}{10}$

If f(x)=4x-1 and g(x)=x^2+7 ,find G(f(x))

frutty [35]

Answer:

$g(f(x))=(4x-1)^2+7=16\,x^2-8x+8$

Step-by-step explanation:

Given:

$f(x)=4x-1\\and \\g(x)=x^2+7$

Then the composition of functions:

$g(f(x))=g(4x-1)=(4x-1)^2+7= (16\,x^2-8x+1)+7=16\,x^2-8x+8$

where we have written the final functional expression in its standard form.

Question 5 (1 point) 5 The Cool Shirts company prints personalized designs on T-shirts. The cost y for x shirts with the same de

Sergeeva-Olga [200]

Answer:

y = 8x + 25

Step-by-step explanation:

Using the coordinates (10, 105) and (20, 185)

The standard linear equation is expressed as y = mx+c

m is the slope

c is the intercept

m = 185 - 105/20-10

m = 80/10

m = 8

Get the y-intercept

Since y = mx+c

105 = 8(10) + c

105 = 80 + c

c = 105 - 80

c = 25

Get the required equation

Recall that y = mx+c

y = 8x + 25

Hence the required equation is y = 8x + 25
